93 ciera runs rough

[zeakieb1]

I have 93 ciera idles rough and runs rough . During accelaration to cruising speed it misses really bad but when im crusing at a stedy speed it runs fine. It does not seem to miss at idle some time. I have replaced the plug wires,plugs and fuel filter . The service engine light is not on. I don't know what else to check.

I just read this and i know it was aboiut a year ago, but im having the same problems atm lol

I changed oil/filter / pcv valve /spark plugs and wires and now mine runs rough.

question is what did you do to fix your problem so i may be able to fix mine ?

Thanks

i had the exact same thing, i have racing plugs, wires, coils, exc. and after much deliberation i found out that one of the spark plugs was bad. i changed it then it was perfect!
