S320 MISFIRE
Hello Everybody
I am in desperate need for some help please !
I own a 1995 S320 75000 km with full up to date service history.My problem: in summer our temperature rises to 40 c and then the troubles starts.With the aircon in use the temp rises to 100+ which is fine but then the vehicle will start to misfire. If I stop and turn it off and restart it will go again.The plugs ,suppressors,coil,computer and God knows what else have been replaced but to no avail.This problem only occurs in summer.
Can somebody please help

RE: S320 MISFIRE
First guess.
Cranks Position Sensor? If no codes have been set. these tend to become heat sensitive.
But could be
MAF? if a P0170/3 code is set.
If the car misfires a code of some sort should have been set in which case next step is to get the codes read. It will help in reaching the CORRECT diagnosis.
