Why dont you use mode 6 to see if there are any pending codes?also look at your fuel trims in obd2 to verify a lean/rich condition.

Re: 2018 Camaro reduced engine power

Bravo,great catch,usually the usual scenario with warranty you only get paid for the time taken for the repair.
Not all the time in research and testing :roll:

Re: Mercedes B class AMG line diesel auto

Re: Porsche Cayman 3.4 2009 Rough running

Hi Jon,what about the fuel pressure pid does it alter on acceleration?also what about the air flow response when the throttle is actuated?Why not carry out an acceration test and see the reaction response wise from the O2^s and the fuel pressure and air flow.

Re: 2013 Citroen Relay 2.2 puma engine p0016 fault

Hi good morning,check your temp sensors in the exhaust,they default @ 5volts if they stop working,or check the actual back pressure in the exhaust,by drilling suitble holes in the system which can be refilled with weld,after of course checking the cam crank correlation to be correct.

Re: 2008 VW Crafter BJL fuel cut???

Yes it was a pd engine,maybe an AWX,Is it still possible to see the injector current patterns?what style injectors are they? probably peizo crystal on a common rail,you would be able to see any problems in the wave forms,of any electrical anomolys.and if they are shorted,
