Intermittent Engine Juddering

[Mr Roboto]

Before I go to my SEAT dealer can any one offer any possibilities to the following problem.

While I let my car warm up on the drive way the rev's drop down then pick up again.

While accelerating + plus also lifting off the power the eninge starts Juddering.

Also this only happens now and then maybe one or twice a month.

The only mod I had done last was the intake manifold replaced with a poished one which was done by my dealer. (never had this problem before then)

If the coil pack was starting to go would the problem happen all the time

Could it be the throttle body when I had the manifold done.

Any info on what it could be would be helpful

Thanks in advance

Coil pack would show up under load, rather than just randomly.

Is there a possibility of an air leak on one of the gaskets / lines on the inlet manifold?

Vag-Com check is the way forward really.





*Separately, any chance of replacing the missing pictures in your Reader's Rides thread?

Yeah I will pop down to the dealer next weekend for a check up.

But I bet the car will behave but it should have a fault code for them to check.

 

[Mr Roboto]

Well the dealer was no help as there was no fault codes.

I bought a nice after market MAF sensor housing complete with sensor, better than the Bosch one plus also changed my Induction kit.

The Car is running perfectly now!

I used to stick up for K&N but it is true their filters are over oiled. It killed my MAF in under 4000 miles


Any way sorted
