Car Shakes in Idle, runs heavy in low rpm's

TRXrider400 · February 17th, 2011, 12:42 PM

Ok, so i just woke up and went to start my car, it doesnt feel right.. When I let it idle, it shakes pretty bad.. it feels like im in a supped up Muscle car.. when i rev it up to about 2k RPM's it goes away and is smoother.. It also smells like something electical is burning.. I have no idea what is wrong with it. I checked the oil and everything else everything seems to be normal. There is no lights on my dash either.. please help

Have you checked your plugs? I recently changed mine and smelled an electrical type odor. It went away, but if you changed them in the recent past one may not be firing/connect just right. Just a thought...

I also just ran seafoam through my system and have noticed a considerable differencen in terms of smoothness and performance. May be worth a try for under $10 and less then 30 minutes of your time.

TRXrider400 · February 17th, 2011, 03:20 PM

I haven't changed the plugs no, That could be a problem, and Whats this Seafoam stuff?
I called my Step dad who was a mechanic a while back, and he said that if water got into any of the connections or wires, that it could be screwing it up, He said to spray WD40 or silicon grease on it, and it should fix it. I did that, and it helped a little, the car still stutters a little when its idling, but no smell. ( just the oil i spilled on the headers that i couldn't wipe off

)

Dont even look at the plugs. Check for a vacuum leak. Look at all the vacuum hoses coming off your intake manifold. There might be a vacuum diagram under the hood but I can't remember if our car has one.

I had the same problem, just cleaned my iac and maf today and it runs smooth as ever

TRXrider400 · February 17th, 2011, 09:45 PM

Yeah, Im going to check it tomorrow. I just got home from work and its pissing me off.. whenever i slowly step on the gas it like thuds. So i have to go fast and keep the RPM's up

02edge · February 17th, 2011, 10:00 PM

had the same problem the other week turned out it was the plug on the coil came loose took it off sprayed some cleaner let it dry and it worked fine

Mr. Red Pony · February 18th, 2011, 08:34 AM

Vacuum leak..

TRXrider400 · February 18th, 2011, 11:15 AM

Im going to check everything, And look for a Vacuum leak. Let you guys know.

TRXrider400 · February 18th, 2011, 12:36 PM

AHHHA! I found the culprit.. Dead spark plug. I grabbed some 20k Volt Gloves, and started pulling the plug wires from the Ignition Coil. 1 was great, 2 was great, woooah 3 was dead, and 4 was dying as well.. Solved the problem.. Now I just need to Change them all out

gahh. Makes sense though.. its got ~100k miles, and I doubt the last owner ever had them changed, so I guess I have to do it. Thanks for all the help guys

TRXrider400 · February 18th, 2011, 12:40 PM

Errm, One last thing. Anyone know what type of Spark plug it is?

mustangmike! · February 18th, 2011, 01:19 PM

20k volt gloves ? lol

Just go to your local auto store. They can get you a basic brand if you dont want anything special. Just have them look it up
