Hi I have2004 Chrysler crossfire auto when its cold box changes fine after a few minutes it changes up to quick. Had the fluid and filter done no change. It goes up to 5 at 20mph which causes the car to vibrate. Only code that come up was map sensor but runs perfectly any help please.

 

I'd want to instrument at least five things: Throttle Position, RPM, coolant temperature, MAP, and MAF. Something must be going bananas

 

Cheers I might try map sensor as that's the main code that come up. But it runs mint no miss fire starts no probs and it is fine for the first start up.

 

Any chance this problem has set a fault code?

 

Have to have a Merc reader. Just checked on one machine that had no warning lights and Torque Pro found nothing but a Merc reader found 30 separate issues in history. Crossie is really a facelift SLK320 under the skin and has the same computers.

Trouble is that replacing the battery trigger some "low voltage" faults so the Merc advice is to read all codes, save them, then clear them, and see what comes back.
