Title: td5 chugging problem
Post by: pezzol on May 27, 2009, 19:05:57

had my 90csw for nearly a year now and have a problem when I'm at full throttle. it chugs like a missfire quite violently. its only under heavy acceleration at the top of the rev range but in every gear. it also needs nursing on half throttle to get any sort of top speed (80-85 is max). anyone had this prob before or any advice would be appreciated.

Hey

I had the same problem and found that it was to do with the air intake. I had used a smaller diameter section of pipe for my snorkel and it wasnt letting enough air in.
Once i removed this, all was well.

If you havnt played with the air intake then it may be worth while checking the air filter etc.

As for top speed, mine is similar to urs

It could be hitting over boost....

Get a set of mole grips (or similar) and clamp them onto the turbo actuator an inch or so away from itts main body (on the none threaded section) - then try and make the arm extend towards the bulkhead. There should be some resistance, but it should move about 2cm or so. If it doesn't move you've found the problem... and it's usually easy to fix.

Is very common on Td5's!!
