Thanks cn90

My car is also 96 850 2,5 20v ,run close to 230k and need PCV replasement. Serie nr (T) 590408. I only want to purcase the parts I need for total replasement + vacuum lines to be done when IM is loose, cant find out all part no. Newbie to this stuff, so if any of you can help with part no that will ...

Temperature indicator show normal temp. I know I have a vacuum leak at the left side of IM, the usual albow. Will also check the ECT.

Thanks Lee.. Just unpluged the MAF sensor, and my engine did not like that at all. Next step will be cleaning IAC and lubricate all moving parts..

Is it ok to unplug MAF sensor when engine is running?

Thanks..will try to unplug MAF sensor tomorrow, 11:08 PM here right now, and santa is on his way.

Yes, I am sure my module is Jetronic LH 3,2 ( that's what named on it). Get the code from homemade led flashing unit, A very simple one, tink I have a pic, will find out and post it here.

Need some tips where to start searching. Anyone know if there is diagnostic code reader that will work on my car?
