I posted this in the carb forum, but nobody responded. I just got my car past the break in stage, now im having some trouble.
In the morning, its a normal temp outside. MY car starts like a champ, two pumps and then it turns right over. the problem starts a bit afterword about when my choke stops doing what is does, my car seems to not be able to run on its own. The idle will slowly go down unil it stalls. I dunno whats causing it, any ideas.

Another problem i had was when i was ddriving down the highway and about 75 or so. It wasnt anything major, the engine just seemed to surge at cruising speeds. It doesnt do it under any acceleration, its really weird. I think its fuel starvation becuse of a bit of a kink in my rubber fuel line, its not really a kink, just a bend that a bit too sharp.

Third is the oddest problem i think. It may relate to the first porblem. When Ive been driving around, and my car is good and warmed up, sometimes it seems to forget what its supposed to be idling at. Soemtimes ill stop and itll idle at 700 or so, where i set it. Other times, under the same conditions, itll idle at like 450 rpms. Any thoughts on this would be great.

Thanks in advance for any help!

 

Are you still using the ECM with the carb?

 

Whats your timing set to?

 

YEs, Im using the ECm with the carb. My timing is set to, i think it was 6-8* before tdc. i think so at least.

 

You may have to perform the choke adjustment, high idle, and curb idle procedure to verify all is correct before proceeding. If those are all correct, the throttle shaft may be worn, the EGR could be leaking, the PCV could be sticking, among numerous other possibilities.

 

ok, ill do the adjustments today. The choke i did a few days ago. Just to make sure, the curb idle is tthe 2 screws in the left and right side front of the carb? And how do i adjust the fast idle? Cant remember...lol

 

I just had a thought on the problem. How does the EGR valve work? I know that it recycles exhaust into the combustion cycle, but how is it controlled? I was looking arond under my hood today, and I realized that there is nothing hooked to the egr? Is it self governing? If its not, Where is the sensor that controls it? thanks
