Lexus RX 2010-15 :: F Sport Slow Throttle Response From Standstill
The throttle response from a standstill seems VERY slow. When I push down the accelerator, it seems to go down a good 3-4 inches before I meet any significant resistance, and even then, I can do a good 2 second count before the engine seems to engage. If I am stopped at a light, and I slightly blip the accelerator, then push the pedal down, it does better. But if I am stopped and floor the gas pedal, nothing happens....at ALL...for at least 2 seconds. It is slightly better when in manual, but the issue is enough for even my wife to comment that it takes off very slowly when you first give it gas.

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 :: 1993 - Transmission Fluid Leakage / Hose Broken?
Tranny fluid spews out pretty good underneath. Is it likely a broken hose? Where do I start?
View 3 RepliesTrans Sport :: Sound When Engaging Transmission / Forward And Specially Reverse
Just recently, my '93 transport 3800 has started making weird sounds when engaging transmission , forward...and specially reverse. This is not a transmission problem. It sounds like there is increased torsional movement of the engine/transmission unit and it made me take a look at the engine while would shift in drive and reverse....it does lean much..impressive ..but in fact I do not remember having tried looking for that before...so I cannot compare.
View 9 RepliesTrans Sport :: 3T40 Automatic Transmission Suddenly Won't Engage Drive Or Reverse
This transmission shifted smooth and strong through all gears until today when it stopped all of a sudden to engage either Drive or Reverse. No previous signs of slippage, hesitation, stalling or lack of power whatsoever.
We checked the linkage to the transmission and it works as intended, nothing loose or broken, everything is in place. If there was something slightly different with it from other similar vans we have then it had a slightly delayed engagement in Drive (it took a second to engage it after you moved the lever) - on all other vans we have the transmission go into Drive almost instantly.
Van is a '92 Pontiac Trans Sport/Chevrolet Lumina APV with the 3.1L V6 Chevy TBI engine with the 3T40 automatic transaxle. Where we should start tackling this issue?
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.
View 2 RepliesGolf V R32 :: Does Sport Mode Also Affect Throttle Response?
I know that sport mode raises the rpm at which shifts occur, but it feels like this mode also makes the throttle response more sensitive. Though, this could be because Sport keeps the needle in the primo range of the power band.
And at the risk of turning this thread into another topic: Does race, either over revving at a light, or just being passes aggressively and stuff like that? This is somewhat geographically dependent. I am originally from PA and live here now and people try and race me all the time, or drive more agressively around me than I feel they otherwise would were in a less sick car.
Golf/GTI VI :: Harsh Engagement Of Transmission
I have a 2012 2.5 with auto trans and am experiencing a problem. After coming to a stop and easing pressure from the brake pedal, if you re-apply pressure you feel a harsh engagement of the transmission, feels like you put it in neutral and then back in drive. Sometimes it will do it while stopped with no change in pedal pressure and feels like someone rear ended you.

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.
View 9 RepliesTrans Sport :: 92 TS 3.8L - Car Is Overheating / Fan Won't Come On
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 RepliesPassat (B6) :: Transmission Having Delayed Engagement When Shifting Into Reverse And Drive
I bought my '07 Passat 2.0T Wagon as a CPOVW 6 weeks ago. It had 4700 miles on it. I complained about the transmission having a delayed engagement when shifting into reverse and drive. (it drives normally however with positive shifts and is very enjoyable) I was told it was normal and not to worry. (could it be designed-in to soften the engagement?).
This week I noticed a light "thunk" in the right front when re-applying power while coasting below 40 MPH. I never noticed it before but I usually strive for smooth driving so that may be why. I've had other Aisin Warners but they were in Volvos. I got out of a '99 Volvo Cross Country because I didn't trust the driveline. Am I going down the same road?
Trans 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 :: 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...

My 92 transport 3.1L had started quitting on me while driving. After sitting for about 15mins I could get it started and then continue on driving. Now its doing it more and I can't take the chance of going anywhere in it.
Got a CEL so I flashed codes 34, and 45. Where to start troubleshooting with what these codes are saying that I should do?
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 :: 1995 APV 3.8 - Vibrations Coming From The Puller Fan
I have a 95 Lumina APV 3.8 and have vibration coming from the puller fan (passenger side front of radiator). Inspection shows fan and motor good, the rubber mounting grommets are hard as nails.
Is there a secret source for these parts?
