Hi Rihnoman, thanks for taking the time to reply.

I have checked your figures and can give you some figures from our diagnostic check. We are using carman scan VCi but some of the figures/values are no available from our kit

Engine speed - 697 rpm

ECT - 75.22 c

IAT - not available

TP Angle -  your measurement is in % ours is in degrees. I feel we do not have the TPS set up right and some help on this would be good. Our reading is 1.95 degrees

H02s Sensor 1 991 mv

Spark - 6.25 BTDC

The MAF readings concern me, we have put a new after market MAF on from a guy in Spain but we have been caught on other makes of cars when a cheapo MAF has been used, we now try to fit branded units if poss but this was not an option as they are difficult to find. Some help with setting the TPS would be good. Also the black plastic posidrive idle screw in the inlet manifold, should this be screwed all the way in tight?

Thanks for your time, it is very much appreciated, this has been an ongoing problem with this vehicle for a while and it would be good to get it sorted.

Yes, check it at idle with the engine warmed up.

Hi.

We have a 1997 Suzuki Vitara 16v. It overfuels badly when the air flow meter is connected. If we disconnect it it runs well, although the fuel consumption is slightly high. We have replaced the airflow meter with a new new unit, not gen Suzuki, aftermarket but the results are the same. I have checked coolant temp sensor and it appears to be reading ok. No fault codes to go on when all connected up. Could we have an ecu fault? Anyone come across anyhting similar. Any help gratefully appreciated.

Have you checked that you are getting the correct reading from the airflow meter? Fully warmed up at ide the airflow should be approx. 3.1g/s and the O2S should be activated:
