#210 of 219 Engine miss at certain speeds.
Nov 06, 2008 (6:04 am)
I have a 1999 Lumina LS w/3.1V6. It has 113K km (70k mi). I am in Canada so metric everything. I assume, based what I have read, it has the 4T65-E transmission. Its about three months now that I am having intermittent missing from the engine at certain speeds, namely 70 km (42mi) or higher.
With a cold car all is good. After a few miles it starts to intermittently miss and at certain circumstances. It is used mainly for work commute and is rarely used over 50 mph. At below 70kph (42mph) no problems. Starts are good, shifts are good (with the occasional hard shift) nothing exciting. When I get to the end of the 70k zone and accelerate gently, primarily uphill onramps, it will occasionally jerk numerous times, shift up then silence.
I brought it to a transmisison shop. They drove it and said it shifted fine. They recommended a fuel filter change and plug/wire verification. Since it was the cheapest route I did. New fuel filter and plugs/wires were checked. It "seemed" to respond better to shifts so i thought case closed. That was 2 weeks ago. Yesterday it did it again.
btw, The transmission oil was flushed at roughly 75k km (46.5k mi). It was done at a Penzoil location. They did NOT change the filter. A machine was plugged into the transmission cooler lines at the rad. They pumped out the old and replaced it with new oil. They said the filter was good for 100k km (60k mi).
After some "googling" I came accross something that "seems" to point to the problem.
At "autos.msn.com" there was something about the 1997 Lumina that talks about "can cause the vehicle to loose TCC operation or feel like an engine miss while driving between 40 and 60 mph." It talks about a TCC Regulator Valve. The 1999 write-up talks about a Transmission Pressure Control Solenoid (PCS). With all I have read 2 TSBs were mentioned:
00-07-30-002B & 02-07-30-022B
Other items I did read was that another filter/oil change might help since it may be a sticking internal valve and a filter change (since it was never done) would help. I called GM and a tranny mech. pointed out that oil/filter change would not help.
I went as far as got my hands on a engine computer, to check if any codes were registered. Nothing
I am at a standpoint. The car is well maintained and changing the car at this point is out of the question (if possible). Dropping in a new tranny (~$2000) would cost more than the value of the car. With it's low mileage for its age it's a shame to dump it.
Any advise would be GREATLY appreciated.

Lumina - we have had our daughter's car in the shop since late August and just received it back. It too had engine stall once reaching passing gear. After much trial and error and $1450 it is working again. The mechanics discovered 4 of 6 fuel wires were shorting out once it warmed up. Hope this helps you.

#217 of 219 Cannot read error codes on 94 Lumina minivan
Aug 29, 2011 (4:18 pm)
I have tried grounding the B pin on the diagnostic connector and with the key on and not started and cannot get the error codes to flash. There are only 3 slots in the connector that have a terminal in them, the two on the right and one two positions from the left on the bottom. I have done some research and I know one of them should be grounded with the key in the on position but I cannot get any codes to read by grounding an of them. Help please.

I just bought a 1994 chevy Lumina off of a older guy who seemed trustworthy. The car looks great and we went on a short test drive and it ran great. He did tell me about it "cutting out on rare occasion" and said it happens after longer drives. I've had the car a week and my work is 3.9 miles away. For the first 3 miles in the morning it runs great, then after that it stalls out. It won't restart without giving it gas and reving the engine, but as soon as my foot goes off the gas, again it stalls. I've also revved it up after a stall and putting it in gear. The car will cough and accelerate off and on like a bull bucking, and then sometimes it stops and runs fine for another 2 or 3 miles before it starts stalling again. I have the same problem as you, it sounds like. Ive sunk all my money into the car and car insurance. I was told from someone at work that the car is notorious for rusting in the fuel filter. He said find the fuel filter and see if its rusted or just replace it. If that doesn't work try a new fuel pump.mI just don't know. I can't figure out why it runs perfectly for the first 5 minutes and then keeps stalling. Could it be a clogged fuel injector, an air sensor or what that other guy said about the fuel lines failing when it gets hot. Let me know what you think. Help please anyone, I don't have much money and this damm car is gonna cost me my new job by making me late or not getting me there!!

Ok here's my problem. I have a 95 lumina car with a3.1 it idles rough no smoke sputters a little but mainly my big problem is when I drive it I can go up to 49mph with no problems when I hit 50mph it starts shaking when in cruising gear no problems or shaking while accelerating if you go 60 and hold it shakes a little less and 80 you can feel it but it's very slight. It is driving me nuts it's not the tires or wheel it's deff an engine problem. I have replaced the plugs wires, coolant temp sensor, fuel filter, PVC, tps, and the maf, still no change I have ran chevron fuel system treatment threw it also just got an oil change which they added Lucius oil treatment. Any help on with I would have this shaking at 50 would really be helpful again I can cruise at 0-49 with no shaking ..
