My 95 Cadillac DeVille why on the interstate all of a sudden lost power started stalling in backfiring it wouldn't die but when I let off the gas and push it again it done nothing not rev up not anything just more backfiring after about three or four minutes it straightens itself out and takes off and then it'll be about a week or so before it does it again this last time it done it bad and blew the muffler open also each morning when I started up I have to rub the engine up for like 5 minutes before it idles I only use high grade has the person who had it before me replace water pump and s few other parts

So I ran the codes on my Cadillac through the onboard dash monitor system and it threw a ro26 and a to37 as active and then it's through a r025 in the past a p o 52 and a po25 but I cannot find what that means anyway

Also io52

Proof reading before you post will keep us less confused.

TO37. RO26 ACTIVE IO52 PO25 PO52

And that's man

Your car uses the pre-1996 OBD1 diagnostic codes. Google "gm obd1 diagnostic codes".

Forget the preceding letters and there are no "o" or "0" characters before the two-digit code numbers in these code lists.



From Post #6 - I Googled it for you.

So does the letters before the numbers not matter?

Because I googled it to but there is no R or T letters before the numbers so I figured it wasn't the right one

Hmmmmmm - - - Looks as if the 4.9 or mid-'90s Deville series has its own code definitions???

Starting in 1994 GM started migrating from OBD-I to the EPA mandate for OBD-II of 1996
GM took certain models and began that process in 1994

Good example the 1994 C4 ZR-1 still used a ECM with a memcal and E-prom where calibration is
BUT all other Corvette models for that year were now with a PCM (flash memory) and all OBD-II codes
That made it worse both PCM and ECM based Corvettes in 1994 used the 16 pin DLC for OBD-II even though the ZR-1 still had a ECM

I suspect anytime the DTCs start with a P, that is OBD-II but again real murky in 94-95 which each model had.

IIRC we went through this diagnostics protocol flap on codes back in the mid-2000s. I bookmarked this thread for future use in these forums.
