Fast Idle Problems
I am trying to get my car running right. Took it to a garage to get a tune up because the Rochester that I just put on didn't seem to be working properly. The garage set the timing, added a new pot to the vacuum advance on the distributor and got the choke working properly. The problem is that they idled the car way too high to prevent stalling when it is in gear (automatic). When I got home I re-adjusted the idle set screw to what seemed a more proper RPM and then when putting it into drive the load from the tranny makes it want to stall.
First, I think the carb might be the problem because I haven't been through it and it is a reproduction that I bought. Tomorrow I am going to throw on another carb on the car to see if that makes a difference. They did look at the carb and made some adjustments and set the air/fuel.
The reason I took it in in the first place is that it has a huge bog when you nail the pedal from a dead stop. The car continues to do that even now that it is back from the shop. Their explanation is that the vacuum is to low at idle because of the RAIV cam. I realize that the vacuum is low at idle but there has to be another explanation. They say you have to bring the rpm's up on the engine to create vacuum and then nail it. That takes a lot of fun out of driving the car as it has a 4.33 rear axle and shifts into second gear real quick. Right now it is making very little power initially which isn't right.
I am also wondering if the RAIV automatic cars used a fast idle solenoid which would kick in when the transmission was is gear to compensate for the load? How would that be wired? It would only need to kick in when the car is in gear. I am kind of grasping at straws at this point.
I know that that car should go like a scared cat when I nail it but I am not there yet. Not sure if a solenoid is necessary
Any suggestion or help would be appreciated.
