I have a 92 Lumina 3.1L. It stalls when I put it in gear. It has stalled driving but restarted on its own. I have changed my MAP sensor, TPS, plugs, unpluggeg my TCC solenoid, and it still stalls.
I ran some seafoam through the
vacuum line from my intake to my
brake booster and a week later it
started to stall. I am at a loss. I also
checked my vacuum lines for leaks
and there is none. I am at a loss and I
dont have the money to buy a new
car. I dont get any help from anyone
monetarily. If I dont get this fixed I
cant see my kids. Please help here is
my number for faster help. 616 551
9137. As soon as I get it back on the
road I can get the VA to help.
My first guess is that the spark plugs are fouled from the Seafoam and not firing correctly. What prompted you to do the Seafoam treatment? Were you having another issue or was this just a preventative maintenance thing? HTH. -Jim
It idles fine and when I press the gas it revs fine. Yes preventive measures.
Have you checked the IAC (idle air control) valve? That could definitely make it stall. HTH. -Jim
I am changing that Friday.
Ok, good. Is the check engine or service engine soon light on? -Jim
It was reading code 23 and last night it read code 33. I know what they are and I changed the MAP sensor (33) but still flashes. I pulled the new MAP out and put my old one in. I will put the new one back in and reset the code.
Code 23 is intake air temperature sensor circuit and code 33 as you said is MAP sensor (signal voltage high). Check the vacuum hose going to the MAP sensor. Be sure it's in good condition and goes directly to the intake manifold. Check the wiring and plug at the intake air temperature sensor. Make sure it's in good condition. HTH. - Jim
Did you ever fix your problem? I am having the same issue with my 94 Chevy Lumina 3.1
