#3476 of 3508 1992 Buick Regal Stalling and Restarting problems HELP!!!!
Apr 25, 2010 (1:39 am)
Hello, I have a 1992 Buick Regal with the 3.8 motor which has a slight hesitation at idle, it will run for awhile and then shut down. It smells rich of fuel and when you pull the plugs they are wet. The fuel pressure test good at 41psi, when ohming out the coils they seem all consistant at .05ohms. Which I cant see all three of them going bad at the same time. The ignition module, Tps sensor, o2 sensor, Knock sensor, camshaft position sensor, plugs, and plug wires have all been replaced with new. If you leave it sit for awhile and go back, it will start back up and then have the same symptoms. When putting in the new plugs and wires, I verified that the plugs were gapped correctly and then sparking good by leaning one on the side of the block. They worked good for a bit and then fouled again. No codes have been thrown either on the obd 1. I sprayed some fluid around upper intake manifold to see if the I could catch some type of vaccum leak or gasket failure to no luck,,,Upper intake manifold is aluminum and I dont believe these are the ones in question for gasket and manifold failure........ANY HELP WOULD GREATLY BE APPRECIATED!!!!

Most are simple up front. The biggest difficulty are the ones in back and especially the one that is right next to the O2 sensor. Also I will say if it is anything like mine the wires will be tuff to get off the first time. I would advise you to change the wires at the same time. If you do choose to do the wires, do one at a time so you don't mix up the fireing order. Just compare the lengths. Best of luck!

You got screwed. My Buick dealership wanted $189 to change out all 6 plugs.

Sounds like a heater core leak.
#3484 of 3508 2001 Regal P0440 Check Engine Light
May 19, 2010 (3:50 am)
So my check engine light comes on after my fuel gage goes to 3/4 or less on my 2001 Regal, non supercharged 3.8 liter. It throws a code P0440 which is evaporative emission control system. If I keep the tank full to 3/4 full, it eventually shuts off and stays off. I tried a new gas cap but it didn't fix the problem.
Any idea what it could be? Thanks!

Just a guess.. low pressure from fuel pump.
