[mneal2_92788]

well when i am driving, my car kicks, like only until i get to a certain rpm. and when i idle, it drops from 800 to 600, shakes and goes back up. it does this while idle ing. when i get to 4th and 5th gear it doesnt do it. anyone know what it is? i think i have a bad spark plug or wire. idk tho

thanx in advance for help

It could be a spark issue. Is your timing advanced, because mine done the same thing when I advanced mine to 20+ BTDC. Ran fine, just missed like crazy while idling.

my car does that when i'm good amount over due on an oil change, then i change the oil and that goes away....how long have you had this problem

Check to make sure the wire going from the coil to the distributor is on tight

it started yesterday, my oil is 1500 miles old. my timing is stock, no upgrades on the car at all. could it be the feul emisions? my engine check light came on just recently, like 25 min ago. i am going to go get it looked at by the dr's...agian. this thing is getting to be a pain, fix one thing, another dies. well its 14, its gotta get better sometime. but anyone with help? so i can get a guess on the fixing price before i am over charged like a b-i.

o2 sensor? egr?

Sounds like an egr problem or something wrong with a sensor (like coolant sensor).
