Ranter Posted April 18, 2017 Share Posted April 18, 2017 Compression test? Also total long shot but I was duped by faulty new plugs last week, which led me down a long road before I decided to recheck them. They should give you info as to what cylinder is at fault or if its all of them anyway. Quote Link to comment Share on other sites More sharing options...
Scrubb Posted April 20, 2017 Author Share Posted April 20, 2017 Yeah, good ideas. I'll do a compression test when I can get access to a tester and I'll check my plugs are working, too. Might as well rule them out since it's easy! Quote Link to comment Share on other sites More sharing options...
Scrubb Posted April 24, 2017 Author Share Posted April 24, 2017 So I managed to pull the fault codes off it today and this was the result: 1. O2 sensor (This only came up once each time I started the engine, which is weird because the other codes were persistent) 3. Mass Air Flow Sensor 5. Throttle Position Sensor Tomorrow I'm going to have another look at the air flow sensor and see if I can clean it better and also attempt to adjust/reset the TPS and hopefully soon I'll get a pipe to put in place of the cat, so I can eliminate that and see where I end up. Hopefully the Air flow sensor is okay as it seems impossible to find one of those! Quote Link to comment Share on other sites More sharing options...
kempy Posted April 25, 2017 Share Posted April 25, 2017 I had a play with the Cordia today, one of the fuel injector plugs had some corrosion and a crack, cleaned it up and the car is going much better, might be something to look at.

Scrubb Posted May 4, 2017 Author Share Posted May 4, 2017 I've managed to find a brand new OEM Mass Air Flow Sensor so I've bought that. Now I need the oxygen sensor - Is anyone able to assist in sourcing this? I've called BNT New Lynn as OR1ON suggested, but they seemed confused and never called me back. I also can't get any voltage out of my TPS sensor, although the impedance across 2 of the pins changes when I rotate the arm, but doesn't appear to be as smooth as I expect. Is anyone also able to assist in sourcing this? Researching online suggests I can use a TPS from a ~2003 Mazda 323/626/Familiar (Just have o re-wire to fit the Mitsubishi plug), and gives better performance, so this may be even better, but I'm unsure where to go to try and find one, except online, but I don't want to do that and find I pad 3x more than I would have if I got locally.

That makes sense as multiple people here are advising there is a common issue with the injectors, but I'm not getting a code for that, so I'll check that after replacing these sensors. I know for a fact the connectors on my injectors are broken so they do need attention! Quote Link to comment Share on other sites More sharing options...
Transom Posted May 4, 2017 Share Posted May 4, 2017 Aliexpress for cheap 02 sensors and tps find the oem part number and search using that - cheap just takes a week or 2 to get here Quote Link to comment Share on other sites More sharing options...

They don't have different specs? Also, I think I've found the part number for the TPS and I've searched online and don't really feel comfortable paying ~$300 for what seems to be, just a potentiometer! 1987 Cordia TPS - MD614075http://www.ebay.com/itm/MITSUBISHI-OEM-86-88-Tredia-Throttle-Position-Sensor-TPS-MD614075-/262721312235?fits=Make%3AMitsubishi|Model%3AMirage&hash=item3d2b6915eb:g:2sQAAOSwo4pYmaxp&vxp=mtr Quote Link to comment Share on other sites More sharing options...
Transom Posted May 4, 2017 Share Posted May 4, 2017 No you buy the correct o2 sensor and tps from aliexpress china using the original part # to search and identify them then you get the correct sensor with the right range and factory plugs etc my $300 O2 sensor that was $150 on eBay was $40 on aliexpress Quote Link to comment Share on other sites More sharing options...
0R10N Posted May 4, 2017 Share Posted May 4, 2017 @Scrubb can you please PM me your number and I'll get Ant from BNT New Lynn to phone you back directly. The staff there are in the middle of stocktake and probably didn't have a chance to even pass the message on to him (branch manager). They have a few different sensors available. Failing that Rockauto may also have what you need, I recently bought an OEM Denso O2 sensor and a coil unit for an early '80s Mazda turbo engine for a fifth of the quoted price from Petroject.

That'd be great @0R10N! I'll PM you my number now. I have looked at Rockauto and they have a listing for TPS for a Cordia which will probably end up costing about $300! Can't find any O2 sensors unfortunately:http://www.rockauto.com/en/moreinfo.php?pk=943165&cc=1205323&jsn=440 1 hour ago, Transom said: No you buy the correct o2 sensor and tps from aliexpress china using the original part # to search and identify them then you get the correct sensor with the right range and factory plugs etc my $300 O2 sensor that was $150 on eBay was $40 on aliexpress @Transom, I didn't even think to look on Ali Express actually. Just had a look now and they've only got this which I can't be sure is correct as I don't have the part numbers but it may work? I'll keep my eye out on there for automotive goodies Quote Link to comment Share on other sites More sharing options...
Transom Posted May 4, 2017 Share Posted May 4, 2017 Also if if was sold as another name/ brand in the USA then check the listings for that model on rockauto were mitzis sold as dodge or something over there? Quote Link to comment Share on other sites More sharing options...
Scrubb Posted May 4, 2017 Author Share Posted May 4, 2017 Yeah, they have the Chrysler Conquest which is a Starion, but I'm not 100% on parts compatibility between the 2.6L and 1.8L engines Quote Link to comment Share on other sites More sharing options...
Scrubb Posted May 18, 2017 Author Share Posted May 18, 2017 So I've got some new parts and replaced some stuff since I posted last, but I'm still facing more issues. Argh! Mass Air Flow Sensor (Part: E5T00172) which I managed to find on Ebay. I also got the below from rockauto.com as they were less than 1/3 what I would have to pay from NZ. I've only fitted MAS and the oxygen sensor so far... Part Number Part Type Price EA Core EA Quantity Total 1987 CHRYSLER CONQUEST 2.6L 156cid L4 Turbocharged STANDARD MOTOR PRODUCTS AX7 Air Intake / Charge Temperature Sensor AU$ 26.86 AU$ 0.00 1 AU$ 26.86 1987 MITSUBISHI CORDIA 1.8L L4 Turbocharged STANDARD MOTOR PRODUCTS TX32 Temperature Sender / Sensor AU$ 19.33 AU$ 0.00 1 AU$ 19.33 1987 MITSUBISHI STARION 2.6L L4 Turbocharged DENSO 2341052 (234-1052) Oxygen (O2) Sensor AU$ 26.41 AU$ 0.00 1 AU$ 26.41 Shipping Economy (Consolidated) AU$ 19.02 Carrier may collect duty and tax upon delivery   Order Total AU$ 91.62 I have a TPS conversion kit from a Mazda on it's way too, but I'll post about that once I receive it. So, I've replaced the MAS and O2 sensor and this is where I'm still running in to problems. After replacing the two sensors, I used K&N filter cleaning kit and cleaned the foam air filter and re-oiled, cleared the codes and took the car for a drive to get it nice and hot. Once I finished driving I parked it up and checked the codes again and I still had a code for the TPS and ISC, but the MAS code was gone, YAY! But, I checked the codes again today after changing the O2 sensor and the code for the MAS is back and the O2 is not going away once the engine is running like it did before. Does anyone have any input on this? Could the air flow sensor have failed already, or do I need to wait for the new TPS before jumping to conclusions? Any help or input on this is much appreciated. Thanks. Quote Link to comment Share on other sites More sharing options...
tortron Posted May 18, 2017 Share Posted May 18, 2017 you could check the wires to the sensors for continuity, possibly a dodgy plug, connection or wire Quote Link to comment Share on other sites More sharing options...
Scrubb Posted July 24, 2017 Author Share Posted July 24, 2017 So, it appears that the sensor wire for the TPS just started reading correctly one day and has been fine since, so can confirm with an adapter plate made, a TPS from a ~2003 Mazda will fit once the connector for the Mazda TPS is soldered on to the old loom. Now to crack on and try to sort this horrible misfire which is got so bad now I don't want to drive the car! Will start with deleting cat and replacing fuel filter. Thanks for all the advice so far guys Quote Link to comment Share on other sites More sharing options...
