I have a light popping and hesitation when accelerating from 3500 rpm upwards... I have checked a few plugs for fouling.. I am going to clean MAF and change fuel filter any other suggestions....

MAF would be my first guess

What the hell is a "help light"?

All right, I'm just kidding. That's what I got out of the title initially though.

Please see my response in your other thread.

Ditto - if not the plugs, also check our 02 sensors.

Not being mean or anything - but you do know how to tell if a plug is fouled or burnt, right?

oren1966

Yes I know what a fouled plug looks like I am going to check the rest of them... after that the o2 sensor thanks for help

Here is a picture of my plugs they do not look fouled to me,although they do have carbon buildup where you are suppose to put the anti-seize when putting them back in

They have a nice bronzed/brown color at the tip where spark is
