Fat-Tony Member 5,364 Member For: 18y 10m 18d Posted 09/08/07 03:18 AM Share Posted 09/08/07 03:18 AM Its not always Valve spring related..It can be 1 of 2 things.. Valve springs (been mentioned already), or Spark plugs fouling up (didnt you just say you just changed them??)what spark plugs did you put in them, and what gap did they have?My cars had valve springs done, and I've still had the issue, but I've since fixed it..danny.that's what happens when you use cheap sh*t spark plugs hey Link to comment Share on other sites More sharing options...

The problem exists both before and after the plugs where changed. EXRLNT - let me know how you go...I got to get this fixed, it's embarrassing when you blow away a bommerdore and then the car sounds like it's having a nervous breakdown.... Guys do you think its worth trying to get Ford to replace them under warranty (high hopes of that).Ozzie Link to comment Share on other sites More sharing options...

(Assuming its auto), or your just touching the rev limitor if its a manual. Link to comment Share on other sites More sharing options...

(Assuming its auto), or your just touching the rev limitor if its a manual.Tried it... problems still persists... I need to see a doctor.I gave it 2 hard hits before tucking her into bed and it was running that bad that it almost stalled. As it went through the boost it broke traction, no valve bounce though then it was running as if it was running on 3 cylinders.Should I take it back th factory tune?Could it be a dirty throttle body? or fuel filter?Normal driving off boost or even 1/2 to 3/4 thottle on boost still runs smooth as.Ozzie Link to comment Share on other sites More sharing options...

I give it a bit of a rev and it comes good again...... Link to comment Share on other sites More sharing options...

I'm thinking maybe its the ECU with the torque restrictions on the BA Autos?I really don't want to change the value springs if they are not gone.There must be someone out there that has had this issue and fixed it!
