Not a Mustang, but still a Ford.

I have a 93 Ford Taurus with 184,000 miles on the ticker. I bought it 15,000 or 20,000 miles ago, and right when I got it I replaced the air filter, rotor, cap, wires, spark plugs, and an oil change. I have done a few more oil changes since then. I have been driving it while it's still cold without problems. The last couple of weeks it has been sputtering while it's cold (like giving it alot of gas) and just the couple of days ago it has been having an idle surge right when I start it. That surge goes away on its own, but if I try to give it gas to make it go away it just kills the car.

I think it could be the fuel filter being clogged, the cheap spark plugs I bought that are crap, or a sensor going out. I remember when my mustang kept surging and it was the ??TPS?? I don't quite remember if it was or was called TPS. Owell.


What are your thoughts?

I'd do Champion Copper plugs in it, then take your ignition module off and take it up to Autozone and have it tested. Make them test it a bunch of times in a row to get it warmed up, and see if it fails. I've got a box of about 50 bad tfi modules in my garage that I have changed out over time. If it's good, then clean the throttle body out real good, get some MAF cleaner and clean that, and run some seafoam through a vacuum line. That should help at least some!

Oh, also check all of your vacuum lines for cracks, or to see if any are pinched flat like the PCV hose likes to do on 3.0s, and make sure that your MAF elements are spotless and that the intake tube has no leaks whatsoever between MAF and throttle body. I just ran through all of these things on a friend's 92 Taurus, and it runs like a million bucks now.

Wow, thanks for all of that info. I just got a bank account and have to wait ten days for a debit card. I forgot to ask for temp checks.

I do remembering cleaning the MAF and throttle body on my 5.0 and it ran like a champ.
