Help Me

[marni]

ok here goes, mechanic added a thing that adds on to the air sensor (i think it is) when it was on we turned the car on and it obviously started, anyway when we revved it a bit the sensor wasnt sensing the air ratio and the car started to make blow off noises from the air filter and was occasionally blowing some air out of the BOV (thank god we didnt test drive it) anyway we turned the car off and disconnected it and put it all back to how it was before he touched it...

now the F*N thing wont start, it cranks but wont kick over at all, we even pushed it down a hill it wouldnt even jump start...

ok now heres my question, is there some sort of relay or fuse the car could have blown? is it the computer thats fried? any info i would appreciate, it only happened yesterday and shes only been in the driveway for a day and its sending me insane!!!!!!!!!

PLEASE HELP ME!!!!!!

1) find a new mechanic

2) dont buy cheap ebay 15BHP hacks - they are all a load of shit

3) check the wiring in the engine bay, the hack would have been applied to the AFM signal wire, check it

the afm signal could be shorting out, unplug it, when its unplugged the RPM should cap out at 2500rpm but it should start and idle ok with the AFM unplugged

check the water temp sensor, if he was fidding with that and fried something the car wont start with a damaged water temp sensor, again just unplug and see if it starts

the water temp sensor is on the radiator pipe going towards the engine, theres two plugs, you can unplug both to test it easily

4) check all other fuses and sensors that you can see, fuses are in the engine bay, in the boot, and on the right side of the steering column

5) run stock ecu diag

6) take it to another work shop if all else fails

sometimes things are too good to be true aye.

did you give the thing for your mech to fit or did he suggest it? I know when my afm is unplugged the car would start once but after that it won't turn over no matter how many times. they say it should be able to turn over but idle low like paul said but for mine it wont turn over at all. Maybe you killed your afm?

Probably true as well. What kind of mechanic installs something that stops your car running and then leaves you to fix it.

my best guess- the 'chip tuning' company flash tuned the ECU memory chip to give more fuel into the mix, and now your plugs are massively fouled

change/clean the plugs, change back to standard ECU calibration, and get back to us....

Try a new ECU. I had this EXACT problem, air coming back through the pod making a loud bang or pop. In my cefiro.

Turns out my ECU was stuffed.

Bourght a new one, and bang runs fine.
