Hi All!
got a really bad misfire on cylinder 1.
The garage cant find the problem and thought you might have heard of this... they have run a scan on the ecu (dont think it is vag com) and it says closed circuit on injector 1. They have swapped injectors over with no difference. They took the rail off and all injectors are working. Compression on cylinder 1 is down from 140 to 90 psi. my guess is that there is a fault between the ecu and the injector maybe causing it to initially run lean and over time buring the valve seats to reduce compression. Now it does not fire on cylinder 1 at all and stinks of fuel if you drive it. All sparks are strong and coil packs checked.
Any suggestions would be really welcome.
Cheers.
