okay so i was driving to work today on the freeway!! i was going like 80 mph and i punched it to pass a car and all of the sudden my throttle would not respond i was pressing on the gas but it did not accelerate at all it like the engine shut off!!! so i pulled over and came to a complete stop and i heard my engine running so it did not shut off and i pushed the pedal and it responded!!!! lol!! this has happened to me twice already and it has all happened doing the same thing!! my engine runs good and idles good and i scanned it and everything seems fine!! i am thinking that it could be my torque converter!! could the torque converter cause this!! i think its the torque converter because my car will not accelerate untill the auto tranny goes back into first!!

Check your fuel pressure first.

And gotta love LMs.... lol

jc358 · 06-02-2009, 02:34 PM

i will check it but i dont think its a fuel pressure problem because it has only happened twice and both time were at high speeds!! the car idle fine ans starts up fine it does not sputter at all at wot!!

ShowNoMercy · 06-02-2009, 02:35 PM

Well high speeds = WOT no?

Or just cruising, like 80ish?

jc358 · 06-02-2009, 02:38 PM

I think it is a tranmission problem. I have a tranny problem with my 92 volvo 240. When I'd get step on it, the tranny will hang up and not move to 3rd or 4th. At the moment its been sitting parked in my driveway for months now.I have to cycle through the gears to get it to work properly. I'll take it to a tranmission shop one day, though I fully expect to the transmission to be gone thhough, it does have 196k on it. Engine solid though, body is great, interior fine to, so ill prolly just fix it. lol, sorry to take this thread of topic, but yeah have ur tranny inspected.

I had the same thing happen to my 2000 Impala. It could be the tourqe converter. Mine ended up needing a full rebuild but mine was much worse than yours sounds.

Does your car have a tachometer? That will tell you if the engine is running

94 Z28 · 06-03-2009, 04:26 PM

NE Time NE where the original post says that the car does not physicaly shut off it just wont have any throttle reponse. he said he hits the gas and nothing happens but its still running.

sounds like the top speed limiter to me, my 96 did the same thing its only supposed to shut off at like 120 or something and mine kept shutting off at like 90 or so, just felt like a dead petal, fixed mine with the hypertech , but i hear the 93's are different
