My BA XR6T has a really annoying 'surging' feeling when driving her cold. Until about 5 minutes into a drive, or around 1/4 engine temp she just hesitates during acceleration.She doesn't cough or splutter but just really hesitates... Even with a full tank of fuel.Have just done the air filter, brand new NGK spark plugs gapped to 1.1 (running car stock)and brand new ford factory coil packs (all 6) tightened all fittings and hoses. Doing all new coolant and flush tomorrow and oil and oil filter early next week.I'm wondering if this is a fuel system issue? Injectors or fuel pump? Possibly the fuel filter? I think she is due for a new fuel filter pretty shortly, but if that doesn't fix it I'm pretty much out of idea's... Could it be a gearbox issue?It seems when it is at operating temp it is ok - Still a little 'rough' feeling though... Could it be an engine issue? A busted 02 sensor? A shot cat?Thanks guys, I'm pretty lost with this one actually...Cheers! Link to comment Share on other sites More sharing options...

You'd think if it was a fuel filter, pump or cat issue the car would struggle at WOT. Maybe one of the tuners here might be able to help.Benny.

If the element is stuffed it will give you a dud signal and the computer will overfuel in response. Not to hard to replace , and they dont last forever anyway.

itsagoanna Member 6 Member For: 13y 2m 18d Gender: Male Posted 06/02/12 04:52 AM Share Posted 06/02/12 04:52 AM I have same problem with my FG turbo...stock tune, vented BOV to air, and replace air box with high flow pod filter system. Surged with and without mods when cold but just went down to ford and told it was not normal and they are suppost to run smooth even when cold. Vehicle is about 2-3 months out of warranty but was told there is a 'grace' period where ford may still cover under warranty or at least cover cost of parts as long as service history etc is sweet (28,000kms on car and for serviced up to 40,000km handbook service....should be sweet). Fingers crossed they fix it for free! (will be putting vehicle back to standard before I give car to them Also trying to get them to fix the ambient temperature sender (in the left hand mirror) as it reads about 6 degrees on a 40 degree day.Will re-post after next week when they've 'had a look'.

itsagoanna Member 6 Member For: 13y 2m 18d Gender: Male Posted 10/03/12 12:48 PM Share Posted 10/03/12 12:48 PM Got Ford to look over my car, before the car went in they were telling me all about this 'grace' period and how it will most likely be covered...None of it was, they did work without me approving it and gave me a nice bill...another story. Apparently they upgraded the computer on it which was suppost to prevent the surge...it did absolutely nothing, and the temperature sender was stuffed and they wanted $80 to change it...I took about 10 steps over to the parts department and the sender costs $15 so I will be putting it in myself. You think they could put in a $15 sensor to keep the customer happy when its a well known problem with these models!I've never understood why a lot of car yards have such bad service when it comes to warranty work and repairs. It certainly does not make you want to deal with them again! Link to comment Share on other sites More sharing options...
