GET IT CHECKED OUT BEFORE YOU SPEND ANYMORE MONEY!!!

Just to let you know, I did get CEL's a little while back and both had to do with both O2 sensors. I figured that was the problem and replaced them. My car ran smooth as glass after that, but soon fell right back into the surging crap. I have no CEL's at this time. I miss my custon tune, it runs SOOO much better with it! It will start out great with the custom tune re-installed, run like a charm, perfect, then soon start that surging crap. But even worse than with the crappy stock tune. .....

OK, about the mis-fire thing ... I forgot to mention I had a mis-fire code on #3 cylinder. I was using E3 plugs and the one in #3 looked like it had went into meltdown. DAMN, why didn't I mention that before? I have recently went with NGK Iridium's. Number 3 plug was gutted but the engine seemed to run fine and without a dead miss. I checked the plugs because of the mis-fire code. The engine seems to be running fine on the NGK's, except for the afformentioned issues.

Like a dumb ass, I just attributied it to the plug because of all the late reviews on the E3 plug causing problems in vehicles, including mis-fires ... a search in which I conducted AFTER my discovery of my melted plug .. yes, melted, never seen anything like it. It was gutted.

So, now I leaning maybe toward the coil or wire as mentioned before.

I will give you a call Matt, and thank you for your input, I MUCH appreciate it!!

Put stock Motorcrafts back in your car. Our cars seem to like them much better. I heard of SVT's having problems with other plugs.

Slow down there Matt. jaykirs is asking for authorized help from us, not certified help. Yes, all of us agree that doing work with a Certified technician and shop is the way to go, but if we could save a few bucks to at least diagnose the issue a bit or work with others who have had similar problems then it would help us a bit. Any kind of help is helpful.

In this day in age, many people have stepped away from helping others just to help get them by. None of us know each other's financial situations or knowledge of each other's type of car, so, we can't come to a conclusion that any of the help that is given isn't good enough to help the need.

I know that you have a strong feeling towards using certified techs and shops because you also work at one and know the ins and outs of using a tech.

But again, people come to forums to draw several suggestions to draw conclusions from and sometimes for some help when he/she is hurting from any issues we are not reading.

If I had the money, I would take it to a certified tech. Unfortunately I don't, so I am trying to figure out a way of figuring out the problem and replacing the part, or parts as cost efectiveley as I can. I really appreciate all the replies and tips and ideas. My fellow fanatics, YOU ROCK!! Any more thought or ideas, please post away. :-)

Have you checked for a vacuum leak?

[jaykirs]

Yes, there are no vacuum leaks. It must be a sensor. Turbo Tom is thinking about doing a xcal loaner program to help FF members that are in need of help, such as myself. I hope he does, it would help a lot of us FF members with problems we can't figure out on our own.

Though that's not a bad idea ... many people may not know how to read on once they have them in their hand or some may think they can change a parameter or 2 and more likely hurt themselves more than helping.

So, it's an up and down idea.

Be best to just find a datalogger that can record the car's parameters and send them to Tom to get his professional opinion on what's up.
