Engine Performance problem
1990 Chevy Beretta 6 cyl Wheel Drive Type unknown Automatic 165000 miles

Yeah I just purchased the car and the engine sounds good. Except for a noise coming from the pulleys. I think its the harmonic balancer but not sure. But i've been having problems with the car stalling. I'll be driving for a goos while and nothing will happen. BUt it seems that after i've been driving the car and it heats up good it starts to stall. I"ll be coming to a stop and as soon as it slows down even with my foot on the brake it seems to want to jerk forward and then die. And it will crank right back up but as soon as I go to put it in drive or reverse it jerks and dies again. It seems as if I press the gas a little bit and put it in gear it will go but still wants to act like it stalls. Sometimes helping press the gas and put it in gear will help but then sometimes it won't. I'll have to wait 5 or 10 min to get it going. I replaced all the plugs and replaced the fuel filter but it still continues to have this problem. Could it be the tcc solenoid or a fuel pump or could it be something else. Also could it be the harmonic balancer causing it to stall out. I would just like to know the correct answer before I went to fixing or repairing things that needed to get fixed. PLZ HELP

Your problem is a stuck tcc solenoid and I can guide you through disconnecting if you want to do it yourself. It will take you about 5 minutes

Yes I really need the help. I tried to find it but couldn't. I was told you can just disconnect a wire. Is that true

Yes. Open the hood and look down at the transaxle. There is a white electrical plug about 1 square inch. Unplug this connector and the problem is gone.

Stand to the right of the center of hood. Look for the transmission dipstick, it should be red. Follow the dipstick tube down. Where it connects is the transmission. On the transmission is only 1 white electrical plug. Its toward the radiator side.

I unplugged some kinda wire from the back of the engine. Towards the bottom of the car. It had to wires coming out of it. Was that the right one. I think it was a purple and like yellow and something else.

If you still cant find it, I suggest going down to the nearest neighborhood garage and ask the mechanic if he could unplug your tcc solenoid connector and give him $10. It will only take him 30 seconds to do. Thats the easy way.

Ok your on the right track. What you unplugged was the speed sensor. There is only one other electrical plug on the transmission, thats the one we need to find.

So I finally got the tcc unplugged and it seems to be running great now. Next question is after i've unplugged it exactly how much will it drop my gas mileage? Cuz I drive 45 min to and from work everyday.

You are barely going to notice. The solenoid only costs about 60 bucks including the part and the gasket on the side of the transmission if you feel your up to a bigger challenge.

I got the same problem with mine! Same year too!
TCC was unplugged. Took it in for a diagnostic and I was told it was the upper intake gasket. Opened up the intake and the gaskets were fine. So I replaced them to be safe anyways. I checked all my hoses and it still didnt solve my problem. What I did notice though is that my EGR valves gasket is not their anymore. Could this be it?

A leak at the egr valve is a vacuum leak and is surely a problem for making it run lean. Replace the gaskets
