Title: PCM
Post by jonnycab on Aug 9^th, 2006, 11:55pm

I've had a few problems with pinking recently (as most of you know).
I have replaced various parts:-
EGR, IAT, FRPR etc,
but still I have pinking.
I had a new front crankshaft oil seal & lower timing chain cover fitted last week (had oil leak). I did ask the mechanic whether it could be due to a timing chain slipping a cog, & he said that can cause it, but in your case...no...the chains are spot on. (new engine's only done 44,000 miles).
The bits I have replaced so far seem to alleviate the problem for a short while but it always comes back again.
The weird thing is that the pinking is not as bad as it was before I started replacing various bits.
At the moment it only pinks sometimes on light acceleration at low speed (20-30mph).

I'll get to the point now.

Are PCMs inter-changable?
The reason I ask is 'cos I have a spare 2.3 PCM.

If I take the PCM out, & replace it with the spare PCM, will the car still run as normal?

I see no reason why. I would try the ecu rather than the pcm.
