So i have a 98 civic ex completely stock. So today i was driving to work and got to a stop light . My idol drop and engine started to vibrate, no check engine light or suck came on. Then When the light turn green it was fine and the next light i came to it never happen again. This is the first time it has happen to me ? What do you guys think the problem might be ??

 

If it hasn't come back I wouldn't really worry about it.

 

maybe your IAC valve went to low and caused a low idle then corrected itself.

 

Alright riotchild. Im very strict when things happen to my car. It bothers me like crazy lol..but thanks for the advice thoe.

 

Go sit in the corner.

Check your coolant level

Kev

 

My coolent level is full ..same with the tank overflow tank.

 

You're trying to diagnose something that happened once. Not easy to do.

 

How long has it been since you have changed your fuel filter? May be a fuel system issue?

 

I change the fuel filter 2 months ago .. Well today I drove it no problems today

 

How old are your plugs? I would double check to make sure they are tight.

Also, check your wires.

 

clean your IACV. It may be just beginning to get stuck. At this many miles, if it hasn't been clean, then it should be.

 

^Next checkpoint.
