Can anyone offer some advice on fuel injection settings, ignition timing and valve clearances for an S3 2.9ltr. I know what the SH's bible says and the Haynes manuals for the Granada & Sierra and have searched PH's for info. I am looking for a few good tips, things to check and possibly adjust before I send the car to TMS.

I did a long round trip at the weekend, driving on some of my favourite roads in Oxfordshire, Gloucestershire and back home cross country to Leicestershire. The car did not let me down once and it was roof off driving all the way.

However, the engine sounded rough at times, particulary at mid revs (3,000+ rpm) and I could not understand why. The days were hot, so the engine was running at 90 C all the time and seemed worse when at its hottest.

The answer I feel is somewhere in the fuelling & timing area, perhaps influenced by the ECU? Anybody got any good ideas or do I book her into TMS?


Q. Why are blue Chimera drivers so bl**dy miserable. Passed two on Sunday (Fairford/Lechlade & Toddington) and did not get a wave from either of them. Got waves from Morgan drivers, TR drivers, MG drivers, kids on the bus...... They should both have their PH priveleges revoked.

Good answers from both, so thanks.
I think I will do a few more checks at the weekend, put the Gunson fault code tester on again, check the plug leads etc.
Then take a day off from work so that I can take her to the guys at Hinckley and have the car set up properly on a rolling road as suggested.
