Car idles then stall's 3.0 v6
27. Sep 2007 at 20:25

As above. All the vac pipes are in the correct places. No air leaks except for the rear actuator pipe broken but glued back. Adjusted the throttle cable to increase the idle to 1000rpm and now it doesn't stall. Dose this point to the idle valve or something else? I am now starting to get fed up with the stalling and need it sorting out. Please help.

It's worth doing a paperclip check and seeing if you've got any stored fault codes. Kevin

Well we have replaced the crankshaft sensor and the stalling has stopped also cleaned up the MAF sensor which has removed the 74 fault code.

The crank shaft fault code 19 still remains without EML light and the car will not rev over 3500 and accerleration over this point is very juddery and noisy. Up till the 3500 mark seems to be ok and running quite smooth.

Any thoughts greatly apprieciated

Andy & Paul
