Okay i have a 95 mc z34 and when i start it, it dies a few times. Now when i drive those its like the fuel won't register/hesitates. The check engine light comes on then goes off. And after the hesitaion and i take my foot off the pedal its like the car us giving itself some gas!!! Sometimes the car will steal while I'm driving. Basically its the same symtoms of a bad tps. I put a new type and tested it plus my fuel pressure and volume us up to specs and i looked at it with a scope and it wasn't the strongest electrical pattern but ok. Can some please help me out!!!!

 

My brother had the Lumina Z34 with the same exact problem, needless to say, 600 dollars later and a month in the shop, and they never could figure out what was going on with it. He eventually just sold the car and bought a newer model monte.

 

WOW!!! That's messed up. Well I'm going to put in a new fuel pump and ect and of that doesn't fix it than I'm doing the same!!!

Ok i did a lot of testing today and came to find out that the honey comb in my cat is so bad its causing a major restriction which is causing my symptoms and the check engine light to come on/O2 sensor. Luckly i have a brand new cat and resonator but with school and work i just don't have the time!!
