Need GM TBI help

PittSpeed Automotive

I put GM throttle-body injection on my 78 CJ7. It was running great at one time, and now I can’t seem to get it quite right. I really need the expert advice and assistance of someone who is very familiar with 3rd Gen Camaros and/or early 90s GM TBI vehicles in general.

If there is a local shop who is good at this stuff, let me know. I just need some help getting it to finally run like it should.

Thanks,
Jon

I’ll check the TB gasket. Fuel pressure is around 10, I will bump it back up to 13.

should be 10-15 psi

the throttle blad bushings sometime go bad in those. it will feel like the gas pedal is sticking

Thanks for the help guys. If I log data in WinALDL, will you be able to look at it and tell me if you see anything wrong?
