Trans Sport :: 1992 - Electric Windows Started Going Up In Hops
Suddenly both electric windows started going up in hops on our '92 Pontiac Trans Sport SE.
If you leave it for 5-10 min. it would resume normal operation then it freezes again in a few seconds and so on.
- window buttons (left and right) checked-out ok
- driver window motor was changed an year ago - it doesn't have the same wear as the other motor
- both window lift mechanisms and guides are properly lubricated and work smoothly
Trans Sport :: 1992 Pontiac - Cylinder 6 Not Firing When Engine Hot
We have a 1992 Pontiac Trans Sport with the Chevy 3.1 V6 TBI engine.
Engine was running poor because of a faulty Coolant Temperature sensor (rusted-out pins). Changed the sensor and cleaned-out rust from the socket and now it runs smooth when cold with decent acceleration.
Problem is that cylinder #6 is not firing when engine is hot at operating temperature. Engine shakes lightly but performance remains good.
Distributor, rotor, spark plugs, spark plug wires and Oxygen Sensor were all changed 1 week ago with new ACDelco parts. What to check next?
Trans Sport :: 1992 Pontiac - Huge Vacuum Leak And MPG Loss
One of the '92 Pontiac Trans Sports (3.1L V6 engine) had developed a huge thirst - the fuel consumption had doubled along with a serious loss of power. All ignition components - distributor cap, rotor, spark plug wires and oxygen sensor are new ACDelco's.
ECM is not throwing-up any fault codes but we suspect a vacuum leak since this engine runs better with the air intake covered-up almost completely.
Is there any way to trace and fix this kind of issue? Any vacuum diagram for this car - I couldn't seem to find it in the GM Service Manual... How would you suggest we proceed?
Trans Sport :: CEL Started Come On Then Shut Off - EGR Fault
Just recently the CEL started acting...first, would come ON then after some time would shut off....but now it is ON and stable. I was almost sure it had to do with EGR....checked codes and indeed, 55 , large EGR port failure and, accordingly, 56, QUAD driver faulty voltage...obviously because of large EGR port solenoid control. I have not verified the EGR coils yet....will come back later as I'm going out for 2 days.... This is a rather new EGR valve...6 or 7 year old.....and in fact, no more than 25000 miles...probably less...

We have a '92 Pontiac Trans Sport with a 3.1L V6 TBI engine. Last Sunday evening it refused to start like someone left the transmission in Drive and the Park/Neutral switch was preventing it to start. There's the buzz sound from the fuel pump when you put the key on then nothing when you turn it to start the engine.
I checked the Park/Neutral swith by connecting an ALDL cable to the OBD port and it indicates correctly when I move the lever to Drive or Parking/Neutral. The only error code stored is "Fuel Pump Relay" but the Fuel Pump appear to be working?!
Battery is good, fuel pump fuse intact and the Park/Neutral switch appear to be working. How we can tackle this problem?
Trans Sport :: Pontiac 2.3 16v- Engine Stopped When Driving / Could Not Start

View 3 RepliesTrans Sport :: 1995 Just Quit Driving Down The Road / Would Not Restart
My 1995 TS with 3.8 just quit driving down the road, would not restart. had to be towed home.
Fuel pressure just meets specs at 41 PSI engine off ( Gm says 41 to 47), but has been that way for some time. Put Actron scan tool on, got a code 361, EST not toggling. GM has no code 361, but based on past experience, this has usually pointed to a defective ignition module, and I thought that was that. While testing, scan tool kept losing communications and having to be reset.
Finally I unplugged power source of tool, and engine immediately quit and would not restart. Resetting scan tool would allow engine to restart, albeit very rough. Doing a wiggle test of engine wiring harness makes no change.
Crank sensor was replaced, about 12 years ago, so it not the trouble prone OEM; cam sensor about 10 years ago by a garage who was unsuccessful in solving a driveability issue.
Issue here is why would scan tool affect engine operation?
Trans Sport :: 3t40 - Trans Slips When In Reverse Under Load?
If I press the gas a little hard in drive, my tires squeal but if I'm in reverse I can feel a slipping in the trans. If I try to back a trailer up an inclined driveway, it won't go, the trans slips. I have no crud in the pan. I've replaced the reverse boost valve. I installed a Trans-Go kit which is suppose to eliminate the reverse slip but it hasn't worked. Everything else works just fine and my fluid is red. I have engine braking in 2nd and 1st. The van backs up fine, it just does this in reverse under load.

I have a 92 ranger 6cyl 4L. The truck stopped running while driving then kicked on again, it did this several times over about 20 minutes then finally died and now I can't get it started. I recently replaced the fuel pump and filter and spark plugs and wires. I get spark if I ground the plug and some gas will pour out of the fuel pressure test valve when I stick a screws driver in. When I check engine codes I get an all pass. Truck will turn over and sometimes run for 2 or 3 seconds but that is it.
View 2 RepliesTrans Sport :: ELC Exhausts Air When Key Is Off?
My Haynes manual indicates that the ELC exhausts air when the key is off. Is it intended to exhaust all air from the shocks every time I stop? It doesn't make sense to lower the vehicle every time I stop for fuel etc. With over 200k miles on this can it's amazing that the compressor still works.

I am working on my daughter's TS, it has been overheating. Water pump is fine and the thermostat is working fine also. I did notice that the temp gauge on the dash isn't. I have noticed that the fan isn't coming on either. I don't have a book on this car or a owners manual. So I am unsure of which fuses to check. I did try turning on the AC to MAX to see if that would start a fan, and that didn't work either.
View 13 RepliesTrans Sport :: 1994 - Oil Puddle Underneath The Car
I replaced my '94 TS intake plenum and upper and lower intake gaskets last year, and as part of the procedure I replaced the badly-degraded rubber gaskets that go at both ends of the manifold (at both ends of the "V", one under the throttle body, one under the PCV valve or so).
A little more than one month ago I realized the oil puddle underneath the car contained -besides power steering fluid from a known leak- motor oil. When I investigated the origin of the leak, I discovered the <> rubber gaskets have disintegrated AGAIN.
I don't see how this gaskets could be installed incorrectly, so I have to conclude the gaskets that came with the kit I used (Felpro?) did not withstand the oil as they should. Either way, I need to replace those <> pieces of rubber again
Now: since I don't want to be doing the same thing every 5 k miles, any good brand for these gaskets? Is there a material (neoprene?) that would last longer in contact with the oil?
Trans Sport :: 95 TS 3.8L Misfire When Reverse Is Applied
My 95 TS 3.8L is misfiring on #4cyl ONLY when reverse is applied. When car is in reverse with parking brake applied, consistently misfires on #4. In drive with brake applied and engine load no miss. Neutral no miss.
Car drive ability is great in drive no misfires. 100% misfires on #4 only when in reverse. Is there any vacuum change or assist utilized with this trans? Possibly vacuum leak? I do not have a vacuum gauge. I changed to a different plug wire and same problem. New plugs installed. Have not swapped coils yet.
I am not familiar with this trans, other than the vacuum servo for upshifting I replaced when it was sucking up trans fluid like my old Powerglide in the OLD days.
Trans Sport :: No More Front Ventilation When Engine Is Hot
These super-hot days our TS had started to develop a very strange problem:
- when you first start the engine the A/C works normally and cold air blows from the front vents on A/C or MAX as usual
- if we shut-down the engine and try to engage A/C or MAX again the cold air would only come-out through the top (windshield) and low vents - no more front ventilation
- all solenoids appear to be working (moving)
Trans Sport :: 1995 TS 3.8 - Slow Cranking When Hot
Our 95 TS 3.8 runs hot. I dislike the 195 Thermostat, but winter is coming. Temps can soar to 230 on gauge, with no air.(Now I remember why I had a 180degree thermostat).
I recently replaced a rebuilt delco starter that was about a year old.(faulty solenoid). I cannot recall if the Slow crank problem was there prior. When 230 degrees, intermittently I get a slow crank with dimming of dashboard lights, but bright headlights.
1. I know that the temps are supposed to swing a lot with this vehicle, but 75 degree days, 230 degrees when in heavy traffic is pushing it.(gauge). Is this normal for 195 thermostat?
2. Possible bad windings on new rebuilt starter? Armature drawing excessive amps when hot? Battery cables look okay, but original.
3. Considering a NEW starter and a heat reflector wrap for starter. New battery cables-thicker cable if possible(used welding cable for my old 421S.D.
Trans Sport :: 1994 TP 3.8 - Overheating In 2 Minutes From Cold
I've replaced the drain plug, filled up the radiator with proper coolant/antifreeze, turned on the engine then closed the cap to see the needle going fast to near the red mark. I turned off the engine and touched the cap with my finger but it was cold so I did the same with a hose, not hot.
Well, it seems the problem was not all circuit was filled. I did add more after a while running and now it is working normally (knock wood).
Trans Sport :: 3.1L V6 - Misfires / Hesitation And Lack Of Power When Hot
Here is one of the nicest-running van we ever had with a 3.1L V6 TBI Chevrolet engine that always ran too good to be true.
Few days ago it developed a misfire condition that is very pronounced when the engine is hot/at operating temperature - under load it hesitates like it's running in 4 cylinders out of 6. When cold it starts right away and runs good & smooth.
Now the van can't go anywhere - it misfires so severely that the engine stalls and dies at idle.
What we tried so far, to no effect, was:
- changing the spark plugs & wires
- replace the distributor cap & rotor
- replaced the EGR valve
- replaced the IAC valve
- replaced the MAP sensor
We had a lot of 3.1L Chevy TBI engines and none ran so smooth like this one and, all of a sudden, none ran that bad in such a short time...
Trans Sport :: Slow Transmission Response Before First Engagement
From time to time, the first time the car is started in a day, the transmission (4T60E, 1993) may take several ............ seconds before first engagement, either in forward or reverse. Fluid level OK, color OK, filter changed 2/3 years ago. This began just a few months ago. After that, everything will work flawlessly for all the day , no problem at all, all shifts OK, all subsequent starts OK.
