I could use some ideas. I have a 1993 Chevrolet Lumina Euro 3.4. Runs awsome as long as I’m on the gas but when I have to stop, the engine dies. Doesn’t idle well. It did this when I first got it and stopped. I put a high flow intake on it hasn’t run right since. The air flow sensor and crakcase vet have been moved properly. Any ideas? ---

Take the aftermarket intake off and check the IAC valve. ---

Cleaned the IAC valve when it was doing this before. Didn’t seem to make any difference. Might try replacing it. Taking off intake will be a last resort. Never had any problems with other intakes that I have changed. Have an ignition module ordered for it but want to get it to return to idle first. It will idle when I sart it. It won’t return to idle. ---

Just in case antone is having the same issues… I disconected a battery terminal and left it over night. Hooked it back up the next day, started the car and let it run for several minutes. It took a couple of starts for the computer to reprogram itself. This seems to have corrected the problem. I guess it takes a Chevy longer than a Ford to reset the computer. ---

That’s a great result! Why did you disconnect the battery? Yes, the engine computer may have needed to be reset to zero, because of the new intake manifold, by disconnecting the battery. A defective throttle position sensor is also a suspect when idle can’t be found. ---

I’ll do the same thing when I get stumped on a problem. It is the same a re-booting the home computer. Sometimes a bad bit gets locked into a memory slot, and this is the only way to clear it out. On a side note, I’ve had to do a similar thing to my digital thermostat, my satellite reciever, and even my VCR. ---

I usually try that when one doesn’t run right. I did it when I changed intakes but apparently didn’t leave it disconected long enough. I’m used to Fords. They only take a couple of minutes. I’ve always driven Fords. My Jeep Wrangler was the first non Ford vehicle. I love it. Pure off-road machine. This Chevy is only the second non Ford. It’s growing on me. Pretty quick for a V6. Decided I want to see just how much I can get out of it!
