Ok so I figured out why his car ran like crap after it warmed up and wouldn't start hot. I couldn't get any correct OHM readings of the injectors that made any sense good or bad so started checking around the computer and found the computer ground was bad. After I fixed that car ran same but would start no matter how hot it was. So then I rechecked injectors and found cyl 1 6 and 8 we're 9 10 and 11 ohms. The rest were 17 to 18. I know anything under 12 is done so I'm pretty sure I've found the other part of problem to get car running properly. My question is this. Are the injectors from my 89 5.0 the same as the injectors in his 305 and will they work in his trans am. I'm running 24lbs on boost now and know my stock 19lbs ones are fine.
