ok here is my issue it sounds just like yours but you guys can tell me what you think. My car a 1990 Iroc z 5.7 litre TPI car will start and run great untill it warms up then it starts to idle real ruff and if i try to apply throttle at all then it dies. i had coil, module, and cats all checked to no avail. I bought a multimeter and the injectors are as follows.(Cylender) (1)17.0 (3)17.2 (5)7.4 (7)17.2//// (2)17.2 (4)12.6 (6)16 (8)8.8 Seems like i got some bad ones i have also already changed the fuel pump in it because the individual i purchased it from said he already checked and it was bad but that didnt fix it so that was a well spent two days ...need to fix it asap so please help if you can thanx

 

It looks like you need injectors. As to whether that's all you need, I don't think any of us can say.
