Alrighty dear buddies
I replaced the fuel pump with my known good one, and the car ran mint. Idled fine, rev'd fine, etc.
Drove it around a bit, boosted up and was quite a bit quicker than previously (to be expected, it now as a turbo.)
Boost and fuel are still at factory default.
Anyway, tonight I decided to drive it home so I could get the exhaust done tomorrow.
However when I stopped at an intersection, it died. The fact the battery was fucked didn't help.
Swapped in a good battery, but now the car does not want to idle very happily. I had to crank the idle speed up a notch to keep it alive.
Sounds very much like it's dropped a cylinder or 2, but picks them back up once revs are increased.
Ideas???
