I have a 2000 Elantra with 134,000 miles on it. The problem is a
misfire on cylinder 2 (autozone). Originally it was on 1 and 3 I think
(autozone) but disconnecting battery has cleared code. CEL (check
engine light) stays lit, blinks and sometimes turns off for a while.
When I first changed plugs it stayed of for about 100 miles or so.
Problem is I can't notice any performance issues when light is blinking
or otherwise. Car runs as if nothing is wrong. The only slight thing
I notice is at idle, the rpm's move very very slightly from say 800
down to 750. It does this in a rythmic pattern. Almost seems normal
Here is what I have tried so far.
plugs - replaced with new
wires - replaced with new
coil - replaced with used coil
acceration sensor - replaced with new
injector cleaner - lucas and seafoam brand.
It seems like the light is coming on less and is blinking less often.
Could be my imagination though.
I am not the original owner and have only had the car a few weeks.
Any advise is appreciated....
