95 problems

[Johnny95]

Just started working on my 95 gt i just picked up so bear with me cause im discovering little issues here and there. but anyway got the car running, fresh gas and a battery. when the car is cold it runs fine till it warms up then it starts mis firing popping and just runs bad. turn it off and start it and it runs fine for about 45 seconds to a minute then it acts up again. no check engine light comes on but i just purchased a code reader to see if anything comes up should be here friday. so far iv tried the maf sensors and the ignition module and that did nothing plugs dont look horrible some are just a tad oily and dark.. car is all stock minus the cat back (literally there is none).... it has me stumped i dont want to keep buying parts i dont need... Any help would be great thanks. cant wait to get her running right to install turbo.

Timing related? Possible bad harmonic balancer and ur getting detonation. More details would be good

 

[ttocs]

check your tps, how does the rotor/cap/wires/plugs look?

95 problems but a chevy aint one.

When my cars start running like poo, I always give it a fresh tune-up. Plugs, wires, cap, rotor,and fuel filter.Other common problem areas are harmonic balancer (already stated), and the PIP inside distributor.I would look into the PIP first after the tune-up. You have the option of replacing just the PIP but that requires disassembly of the dizzy, OR replaceing the whole dizzy as a unit.

The wires look good just one little spot. The plugs looked ok just a little dark and some were wet kinda oily. I'm going to get some wires, plugs, a whole new dizzy, coil and 02 sensors. I just don't understand why its dosent happen when cold or after the re start

Did you solve the problem?

This sounds alot like that same prob I'm having..

your computor runs in a different mode till its warmed up then it really starts looking at sensors such as the o2

 

[screamin5oh]

yea usually o2's will do what your talking about, also bad plugs will do that, like stated above always change plugs and wires every year on these things, also a dirty maf sensor will make these cars into dogs, take the sensor off and spray it with maf sensor cleaner,

 

[Johnny95]

02 sensors was the fix

good deal man glad u found the problem

Good to hear you fixed it! When mine went bad one of them just sort of fellout happen to look under the car and there it was just hanging 10 from the connector.
