My car idles normal , but rev's somewhat
 

Everytime im idleing at a light, the engine will hiccup a little bit, but the RPM's stay at .5, it will hiccup worse everytime i haul *** on the interstate and go to idle after that.

example: had to get in far left lane 5 lanes over in less than 500 feet, i gun it and get over, at bottom of ramp, i hit red light and idle, the car shutters randomly fiercely for as long as im sitting, when i start to move over 5mph, it stops and everything seems fine.

today, i was getting on the interstate and was at around 70 when the check engine light flickered 3 times, and never turned on again, i tried to slow down and re create the error light, but it didnt do it.

wtf is up ? my car is an auto 99gle w/ 52k on it

anyone with a similar problem?

thx

You have a misfire. Check the ECU for codes. Could be a coil pack.

yea my friends 1995 jeep grand cherokee was doing that last night
it was just in idle then it would self rev from .7 to like 1.5 then go down and do it like a minute later?

what could be the problemo
