Hello,
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 to me.
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.
FALSE MISFIRE?
I am not the original owner and have only had the car a few weeks.
Any advise is appreciated....
