95 camaro running problems
Hello all,
My son's 95 Camaro (3.4L V-6) is giving me some grief. About a
month ago, it would start and immediately die. After troubleshooting it, I
took it to the local mechanic figuring the fuel pump was going (I didn't want to deal with it). It started great for him the next day. It ran great until now:
When it's cold, it starts, but runs rough through all RPM ranges (like a cylinder is missing or it's very rich) until it warms up. Then it runs fine.
If you shut it off and restart it (warm), it takes a few tries before it keeps running (sort of like problem one above).
I've changed the plugs and wires. I've had the upper intake manifold and injector rack off and cleaned and resealed everything. I Ohm'd the fuel injectors and they're all good. I pulled the ingnition coil pack and cleaned and Ohm'd that all out. One coil has slightly higher resistance, but is within limits. O'reilly's tested the ignition control module (it's good).
The coolant temp sensor Ohm's out good.
There has never been a "service engine soon" light ever. Since this is a
95, my code reader, as well as Auto Zone's, etc. can't read the PCM even if there is a code.
I'm not ready to go to the dealer yet to pay for a reading. Any thought's?
Thanks!
