My 2.3 turbo started to act up last week.The turbo set up has been in the Rallye for about 4 years.It is slow to take off, but then when i get on it ,it stumbles and pops through the exhaust. This starts at about 2800 rpm.It idles fine,fuel pressure is at 39 psi.I replaced the plugs,wires, cap and rotor and the fuel pressure regulator.I also removed the air filter just to see if it would make a difference[not].Any body have any clues.I'm about ready to start pulling my hair out.Want to take the Rallye to the all Ford swap meet on Thanksgiving weekend.Have people coming in who want to see it.
Hey Pintoman,
Do you still have the EGR system hooked-up?
From Pintony
If your turbo is a efi set-up I would change the knock sensor (the one on the lower intake, driver's side top and forward). Many turbo people unplug it with no issues, but mine was bad, and it did stuff kind of like what you describe. Not too expensive either, and easy to get at.

Maybe your ignition is not advancing-a vacuum line? Old vacumm lines cause all sorts of problems when they crack in a hard to reach spot-maybe near a heat source- Or your electronic control maybe getting old- sometimes a bad ground in your primary circuit. Tell us what you find, it could be a learning experience for a few of us who are not pros--
Yea still has egr hooked up.I'm planning on replacing the TPI module,the dialectic grease maybe dried out.I will also check out the knock sensor also,can't hurt.As soon as i get it fixed i will post what the problem was.
Hello Pintoman,
Try the easy stuff first.
Remove the vacuum line from your EGR and plug the line.
Re-start or test, trying to re-create the conditions that cause your backfire.

Hey Pintony.Found the problem,could kick myself in the rear.After swapping parts for two weeks,it just fell in my lap.The power wire from the alt. was broken about three inch's inside the split loom.It now runs real good.While I was out road testing it the clutch went south.So now its jacked up waiting for the clutch assembly to come in.
Hey Harley,
Glad to hear you found your backfire problem.
What clutch are you buying?
I just picked up a NEW Centerforce II P.P. But have not decided on a disk yet.
Opinions are welcome.
NOTE: I am using the 9 1/8 clutch

Hey Pintony.I'm using a t-9 out of a XR4ti,the clutch will be here on Tuesday.If you are coming out for the Super Swap on turkey day weekend look me up in the Ag-Hort building.I will be there all weekend.
Hey Harley,
About the Columbus Swap......

Do you have a Swap space?

From Pintony
