Need help
1994 Holden Commodore 6 cyl Automatic
Hi, i have a vr commodore 1994, ive been having problems with the running of my car, i seems like its choking when im driving it now starting to backfire.. i took the car to a mechanic and he put it on a computer and told me i have to replace the car computer which i did and it didnt fix the problem, took the car to an auto elec and he found nothing wrong with the wiring, since then i have replaced crank angle sensor, fuel pump and filter, coil and modular , spark plug leads and spark plugs... and its still doing the same thing , has anyone got any ideas for me to fix this car.. thankyou

Hi there,
I would be checking the air flow meter and the throttle position sensor. also check for a cracked or broken vacuum line at the base of the throttle body.
Run a scan and check for any set fault codes, as the check light will not always come on with a fault, also check that the earth wire at the base of the coil pack is tight and clean. start here.

Hi , i have changed the MAP Sensor and its still the same, thankyou
Have you re scanned for fault codes? and dose your mechanic have a scanner that gives life data, this will help pin point the fault.

Have you checked the coolant temp sensor for correct readings?
