Help with 1994 Nissan Altima, 4.2L, wants to stall

Asked by Dec 08, 2013 at 04:59 PM about the 1994 Nissan Altima GXE

Question type: Maintenance & Repair

Car runs fine, and all the sudden the RPMs drop, but it doesn't stall.  This is a random occurrence.  Sometimes when I put pressure on the gas, I notice it happen, dropping RPMs, but some days it doesn't.  I have no check engine light or codes coming up.  I have changed the spark plugs already.  I have changed the catalytic converter, knowing that's one of the components that will not trigger a code.  I still have the problem. I have added some C foam to the gas to clean the injectors, and I'm going to change the spark plug wires and the gas filter next.  Hopefully this does it.  What else do you suggest?  Checking the gas pressure in the pump? Am I on the right track?  Suggestions?  Thanks.

ummm, the main ground cable 1/0 battery black cable to ground...not the clamp end, but the lug end...unbolt that from the chassis, wirebrush that spot on the chassis, removing corrosion and providing a 300 AMP connection to that lug that you will also wirebrush free of corrosion and make it shiny...put 'em together....fire it up and problems are solved~

"CLEAR the CODES" with a cheap diagnostic scanner~
