Stu Posted August 19, 2010 Share Posted August 19, 2010 Then you have a problem with your car. It didn't do that when it left the factory so really you should look at resolving whatever the issue is than buying aftermarket snake oil. Any sensor on the car when faulty can cause 'flat spots'. Air leaks on the inlet tract can too (in relation to MAF). Best to get a garage to diagnose which sensor is faulty rather than you potentially wasting more money randomly replacing them one by one until it (hopefully) goes away.

alexc1983 Posted August 19, 2010 Share Posted August 19, 2010 yet another tuning con with false claims! dont bother mate. I had similar issues with lambda sensor, engine overfuelling it seemed. Check all your sensors Link to comment Share on other sites More sharing options...

Check all your sensorsi have had the car on diagnostics computer there are no faults with the engine at all Link to comment Share on other sites More sharing options...

Check all your sensorsi have had the car on diagnostics computer there are no faults with the engine at all There's a fault with something if you have a noticeable 'flat spot'. If you've already made your mind up that this valve is going to fix all your 'problems', then just say and we'll tell you what you want to hear.

It needs closer looking at i f the flat spot is anything more than normal (zetecs do have a natural flatspot) then I wouldnt be looking at fitting a FSE valve, all you do with that is risk ruining the fuel pressure.

mrfixit Posted August 19, 2010 Author Share Posted August 19, 2010 the car drives alright there is no fuelling problems it ticks over alright the engine is sound the only thing is when i try to over take she holds back then gos now i understand this to be a flat spot around 3000 revs i have also read it that this is common on gti Link to comment Share on other sites More sharing options...
Stu Posted August 19, 2010 Share Posted August 19, 2010 zetecs do have a natural flatspot You mean this barely noticeable dip in the power curve? http://di.cx/gallery/d/5489-2/eec_vs_ms_rr_01.jpg I doubt anyone is really feeling that in the car.
