Hi my car has been holding back in first and some times second gear and only
boosting to .9 BAR in first but second only holds back some times and the rest of their gears i get 1.4 bar. i got new coil packs , new NGK 7 with a 6 gap, new z32 maf and the lamda is not running on the power fc.
I have been told that their might be an air leak on the system what would be
the best way to check that any ideas will be very appreciated ?

 

hi mate im having the same problem and done all the same things as you apart from the brand new maf sensor been told the same probs got an air leak.

 

hi mate so have you got any ideas on checking for air leak ?

 

i was gonna start with the intercooler hoses wont be till weekend.

 

their must be an easy way to check for an air leak with out dismantling all the intercooler pipes. plus i cant see that my intercooler pipes are leaking may be a vacuum pipe.
come all you guys out their help us out?
