2003 Sebring lxi coupe 3.0 with multiple misfire New distributor (camshaft sensor, coil) New crankshaft sensor New plugs and wires Good compression At idle more rough then when on the gas and seems t


okay, that info is helpful i would have said a coil test but okay with a new distributor it should be good, lets look at the egr valve, with a cold engine start it up and feel the egr tube, this tube feeds exhaust to intake, it should not get hot right away, if it does then egr is open causing misfires, also remove vacuum line from the egr valve just in case it is a bad vacuum solenoid , there should be no vacuum to this vacuum hose with cold engine at idle. let me know the out come.

My 2003 Dodge neon shakes pretty violently while in idle. The acceleration is also off, yesterday I tried to pull out of a gas station and it wouldn't accelerate past 10mph until i hit the brake a


Before you start checking and touching sesitive parts such as map sensors, and 02sensors, or even think of buying $40.00 - $100.00 parts, I'd suggest you scan over all of your vacume lines(hoses), just in case one of them has a hole,cut, or torn. That's what I experienced. My 84 GMC pick-up didn't pass inspection because the check engine light on, and idle was rough and shaking. Everyone was suggesting same parts as here, on my expense. I was a little sceptical on guessing $40.00-$100.00 parts. So the next day I was looking at my engine, and heard a small hissing noise. I followed the noise, and low and behold! A torn 1/2"x 3"-90 digree, $5.00 vacume hose, that was resting above the hot valve cover. Had a small burnt hole. I replaced it,disconnected battery,drove the truck about 45 miles. No ckeck eng. light,smooth idle, and past inspection. Good luck, Frank.

My "Check Engine Light" has gone on periodically


From what you are describing i feel you might be having an bad EGR valve..It only causes the rough idle and shaking and fuel smell in exhaust..It can also cause back firing. Does it happen? Also do you hear any popping noise from exhaust?

It violently shakes when parked or when stopped with brake applied, doesn't shake when moving though, rpms is like 500rpm constant so between 0 and 1 on the gauge. it also notice at night my lights stay...


If it shakes, it is normally either a bad motor mount (if the car runs fine) or your car is "missing" on one or more cylinders (misfire). The belt will squeal because they stretch with use. That can be solved by replacing the belt or tightening the belt. The squealing sound won't go away until you do one of those two things and is unrelated to the shaking. You PROBABLY are experiencing a very "rough idle" if any of the hoses to the intake (top of the motor) have a hole or crack in them from heat or age. This is common and is the first thing to look for to avoid high repair bills. Bad (worn out) spark plugs or old cracked plug wires can also cause a misfire. You could also have a bad coil pack, but mine has gone 186,000 miles without coil replacement or new plugs or wires and I've only changed the fuel filter once. Another possiblity is a faulty Idle Position Sensor that is not properly regulating the fuel delivery. Normally that would cause an engine light to come on also though and you can have someone at the parts store "read the code" once the engine light comes on.

Engine shakes when Idling/ Check Engine Light started blinking


i just fixed a similar problem on my van there is a rubber elbow on the end of the pvc hose that connects to the valve cover you can only buy the elbow with the hose and it costs about 100 bucks but i guess they have had to replace a lot of these because the new one looks twice has strong you just have to check and see if its collapsed in on itself preventing air movement or leaking the shop will charge you 175 dollars to fix it plus the part but it only takes 20 minutes good luck

My Tracker shakes like a wet dog when idling!!


You could check to make sure the plug wires are all intact. If they are, try replacing the wires and plugs. It could also be that the idling is set too low. It could be the mapping sensor as well. Also try, Maybe the coil pack is going bad. It will cause the engine to misfire. The can be bought at Auto Zone or Advanced Auto. Some place like that...
