My 86 Camaro IROC-Z is giving me a load of trouble. It's always had a hard time starting...usually I have to pump the accelerator to get it started.
Now, in the cold weather, it's flooding every time I try to start it. I just gas-fouled a second set of plugs yesterday. It'll stall if I don't keep a little throttle on it for at least 15 minutes while it warms up. It runs rough until it warms up, at which point it seems OK, but this is a pain.
I changed my air filter, thinking it may have been choking off airflow, but it's still acting up. Thinking it may be the carb (Rochester Quadra-Jet w/feedback I think). My guess is that the floats are sticking open, or the fast (choke) idle may be improperly adjusted. Do you think an overhaul/rebuild would be in order?
Also, do I need to change all the plugs (those back ones are an aggravation) or do you think if I got the front 4 in the back ones would clean themselves off once the engine started firing?
And does anyone know if Rochester still makes parts? And if not, do any other companies have a carb that'll work with the ECM in the later-model cars?
Thanks for putting up with me.
