1998 CV P71 Question...

[High-C]

Hey guys… Trust me when I say that I have used the search function at CV.net over the past few days, but I have still found nothing that describes the problem that I am experiencing…

While driving, the car feels like the Torque Converter will very briefly unlock and then the TC (Traction Control) light will come on steady… Within 10-20 seconds, the Check Engine light will come on and the car stalls, at any speed… If I pull over and turn the key off, the lights clear and the cars re-starts as if nothing has happened. I could get 5 miles down the road until it happens again or 500 feet. It actually got progressively worse while limping home (10-15 times) and began happening continuously…

Any thoughts before I start trying things this weekend???

I couldn't get any new codes to come up this weekend... If I pull out the chip, with the Marauder Air Box and larger MAF, will it run correctly or start a whole new problem??? I also need to have the emissions here in Northern Virginia done and I heard that in order for the ECM to talk to the Emissions Machine, I need to either pull the chip or try removing a pin (#13?) on the data port... There were no communications when I had the car at the station... Any thoughts?

[RF Overlord]

Yes, either pull pin 13 on the OBDII port, or get an adapter cable from SCT or from Lidio. I have one of those...inexpensive and works fine.

Would a retune either with the chip or an Xcal solve this?

Remove the MAF, airbox, and chip and you should be good to go. Granted, the plugs are a degree colder but you should be fine running 93.

Once you past emissions, you could then reinstall everything and have the car tuned locally.

Hope this helps. :beer:

Did you drive it around for a few days before you had it inspected? I pulled my tune out before a inspection and the readout said the computer wasnt ready and couldnt do the inspection.

Im not a trans expert, but does it have a TCCS?
Trans Converter Clutch Solenoid.
Could be the issue?

I will add this to my list of possibilities...

[High-C]

I pulled pin #13 and whatever that did, it worked...

I passed VA Emissions yesterday!!!

Thanks for the help guys. I will post up when I figure out the TC issues. I was taking the car into the shop this morning and didn't get more than a 1/4mile from the house before it stalled out. I limped it home so I can mess with it later... That's not a good experience in Northern VA rush hour traffic... :(
