My 1996 3.8 V6 Camaro (78,000 original miles) is very difficult to start when the engine is cold (off as little as 15 minutes). I have to give it a lot of gas too. Then it idles really rough for a few seconds before it finally smoothes out. Sometimes get a cloud of blue smoke shooting out the exaust and the odor of gasoline. If I turn the motor off and immediately start again, it starts just fine (like it should). Also having a terrible miss-fire problem that begun shortly after (related or not?).
This problem seemed to happen suddenly about 4 months ago. Doesn't seem to be getting worse, but is getting to be annoying and embarrasing.
Things I have replaced, repaired or tried during the course of this problem:
1. Replaced spark plugs (with original AC Delco)
2. Replaced wires twice (first ones were cheapies)
3. Replaced fuel filter
4. Inspected fuel injectors
5. Replaced battery
6. Fuel injector cleaner
7. Octane boost
8. Higher grade of fuel (different places)
Haven't retrieved code(s) yet, but just wanted to know if anybody has been experiencing similar problems with the GM 3800 series engine and might be able to share some information or suggestions to remedy this problem.
Thank you for any help.
