Engine Problems

Colin342 · 11-24-2007, 06:05 AM

Hi there, I'm having a problem with my 225 TT. Its 2001 with 70K miles and idle is good warm or cold. Normal operation is good too if I accelerate but when I put my foot down and need a bit more acceleration it appears like I loose a few plugs. I experience a slight juddering but as soon as I get up to speed things are normal.

To me it appears like a plug is breaking down under load but reading some of these entries this may be incorrect.

Can anyone tell me if this is the start of a bigger problem or is this a simpl'ish fix?

Cheers in advance.

Colin

Three days after purchasing my 2001 TT, I had acceleration problems too. Felt like the car had lost 25-40% of its power. Turns out the airflow mass meter had failed. A mate's TT, same age, also had the same prob. Spoke to a dealer and it is something that tends to go.

Also check your lamba probes, ( to do with the cataylatic converter), they can also be prime suspects as if they are giving problems they lag behind during exhaust and starve the engine.

I have an '01 tt and just had to replace the mass air flow sensor also. Do this yourself, I bought the sensor for $240 and put it on in about 5 min, it screws on to the air filter housing.
