Question about 2002 Chevrolet Monte Carlo

2 Answers

2002 ls monte carlo "shudders" between 2,000-2400 rpm.....

Recently, my 2002 monte carlo bega shuddering on accelerating between 2,000-2,400 rpm range...... it consistently does this until you push through it or let off the gas.....but doesn't do it all the time.. I decided to manually put it in first first gear and at that specific rpm range it shudders like mad and even pops out the tailpipe..........



i've had multiple people look at it and hook up scanners to no end... have replaced all sorts of things, that "could" be the cause...multiple sensors, tried different gas... full tune up........ NOTHING has fixed it!
and to make matters worse, will not throw a trouble code....HELP!

My monte carlo would hit 2nd gear and bog down and not shift properly until it got to the last gear. I had the catalytic converter replaced and that fixed that problem. (It also created another, but not near as bad)

I have a 2002 Lincoln LS that up to 3000 rpm seems to run fine. at 3000, it starts to shudder and miss. any ideas/


Yea , take it to a qualified repair shop that has a scan tool that can show misfire data . That's the best way . What engine ? 3.0 L or 3.9 L . Both have COP - coil on plug ignition system . I have replaced a bunch of these coil's an spark plugs . The spark plug get so worn the spark can't jump the gap an fries the coil and if it goes like that long enough it will short out the driver (transistor) in the PCM engine computer . The last one i worked on cost the owner over 2 grand. New computer , programming , new coils , plugs , plus my labor .

If one of the engine components is acting up, you should get a check engine light and have codes for the components. If the light is not coming on, it could be a suspension or mechanical problem.
Low fuel pressure could also do it.

Shudder in mazda tribute


Sounds like the torque converter is chattering and likely will have to be replaced. Have a trans shop verify that. The other problem is a separate question and should be posted that way.

Loss of power in acceleration


I would check the fuel pressure first.
If the engine was miss-firing the check engine light should be on.

Shuddering at 400 rpm


if the engine light is flashing it means that i could be a misfire or a emission problem and its big enough to damage your catalytic converter.
