    Ross thanks for the help on the XLR stuff. I wasn't told that the engines were older. Maybe a year ago I was. Anyway I guess he is looking for some new T-bodies

    Thank You for the welcome!....Great forum and website!....however?...I may be in over my head???....I just picked up an 01 deville dhs for what i think is going to be another hobby car! This car/engine is like from another planet!....lol... Think maybe i should just stick with my 1985 307 riviera?

    I just got car, ran a scan and appears I have to inspect or change crankshaft sensors. code po 336 came up with service soon light.

    car starts runs (fast/slow idle) about 5 minutes, and shuts down.... to re-start you have to turn key off and will then run for hours.

    I would appreciate any info on how to clean/change sensors or any advice as to if i'm on the right track?

    Regards,
    Danny

    You need some crank sensors.
    Look on the Cadillac Owners forum for a how to. Do a search.

    hello everyone, I am new to this site and hopefully found some help. It seems that it has been a few years since this topic was opened. has anybody worked out a simpler controller for the northstar? I have a 2000 4.6 with 4t80 into a VW beetle. had original PCM reprogrammed to run, and it does run!! I would like to install a different PCM that can be easily modified by the local tuning shop. nobody seems to be able to crack this 00 to 04 version. has anyone had success running a newer PCM for only engine and trans control???

    Thanks for the update A.J, I wondered how far you got with those PCM's.
    I no longer monitor the forum, please either post your question or create a support ticket.
