Stalling problem---revisited

Post by 57lxi »

Heres the specs: 95 Olds 88, NA, 165k on the clock. Heres the problem: Stalls out and restarts within a minute or less of cranking. I suspected a bad fuel pump relay, replaced it (thanks guys for telling me where to find it =D> ). All seems fine and stalling problem resurfaces. Here is what happens and "where" I have found the stalling takes place. Dosen't matter if the full tank is full or half full, temp below 200, in town only. Seems to happen when you pull up to a stop light or right after reaching 30-40 mph and backing off to "cruise". No stalling when at 50-90+ on the highway, no jerks, no misses. Pulls strong to speeds that would get you thrown in jail. [-X Today it died and I was able to pull off in a quiet area. I shut the switch down and turned it to the run position, I could hear the fuel pump kick in for 2-3 seconds. Crank, crank, crank, stop. Turn to off for a few seconds, crank, boom, she fires off and I proceed home with no futher issues. I have also been able to fire 'er back up when rolling by just putting in neutral and restarting. Fuel pump less than a year old (Delco). fuel filter with less than 300 miles on it, Delco plugs, battery cables so clean a brain surgeon would use them, alternator output at idle is 13+ volts. I am looking at an upcoming 2400 mile road trip and I don't want my 3.8 dieing in the middle of bumfu-- Colorado. PLEASE don't make me take take the rice-burner Mazada. :hail:

I had the same problem with stalling at stop lights. I would have to keep my foot on the gas to keep the engine idle up while applying the brakes to stop. Turned out to be a TCC locking on in the trans. (Rebuild 1400.00) I would suggest a scan to see if you have any stored codes from your stalls. If you are having the same issue I had you could try some Seafoam Trans Tune...it may buy you a little time.

Re: Stalling problem---revisited---FOUND A TSB #

Post by 57lxi »

Ok guys, need someone with access to TSB's. I found one on Alldata that may point me in the right direction to get mine (and maybe someone elses) stalling issue fixed. TSB #95c11, Dec. 94 specifically addresses stalling on deceleration, which is my problem. :helpsmilie: Anyone?

Its possible that you may need an updated chip... But I'd need to know the numbers off the current chip in the PCM to be able to tell you what you have..

I do agree that the car should be scanned to see what the PCM is seeing and reacting to

I could get you that info. The TSB I mentioned is a saftey recall and if my car has never had it done, then it would be a freebie to get it done. PCM is in the passenger footwell, right?

Correct... Passenger side foot well.. I am also wondering if its the original PCM... These 94-95's seem to have PCM issues..

Re: Stalling problem---revisited----Recall notice found

Post by 57lxi »

It took a little but I found the TSB recall concerning "stalling on deceleration". The TSB covers Pontiac Bonnevilles only but I dont see where haveing an Olds makes a difference.

"Involved are certain 1995 Pontiac Bonneville vehicles equipped with a 3800 Series II engine (RPO36, Vin K) with the following Vin breakpoints: Pontiac Orion S4200007-S4213735".

Cutting thru all the leagl mumbo-jumbo, it says to replace the MEM-CAL chip with an improved version: 16215799 F17 (2.84) BNUW 5714 9674/8764 16215814 FW2, (3.06) BNWB 5764 9664/8764. I can only assumme the 2.84 and 3.06 are axle ratios. It also says, "dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time foward".

My local Pontiac dealers was unable (or unwilling) to pull this TSB up. [-( I will chase this futher when I get back from my 2200 mile roadtrip( I am taking the Olds.) :bow: As I mentioned before, whe it does stall, it will fire right back up and I seem to have found a way around it, snick her into neutral when pulling up to a light or powerbrake just a little. In the meantime, if you "chip" gurus can figure this out, lemme know. IF, I hafta pay for a new chip, I might as well go for the "performance" version. :wink:
