Dangerous problem

[crotchrocket]

GUYS,

i have to tell you your incorrect!!

I had this issue twice but not to the extent satch has. I threw mine into neutral expecting it to rev straight up to the limiter but it didnt. The minute i threw it in neutral the revs died back down. My initial thought was the throttle suddenly jamed open but as i said it died back down in neutral. Thankfully i didnt hit the car infront of me i jammed my foot harder on the brake and grabed the gear lever.

Soon as i put it back in gear it was fine.

it has done it twice now and it was just gentle the second time. No idea what it is though, i know the engine compensates when the fan comes on or the aircon kicks in and wonder if that was the sudden increase in revs?

I tend to put it in neutral when i stop now anyway and havent had the problem since.

it never reves without imput when its in nuetral so cant be anything to do with idle control valve etc so it must be an auxillary thats taxing the engine and the engine imediately tries to compensate by increasing the revs?

Anyone got any ideas??

I'm glad someone brought this problem to our attention. My son is learning to drive and he has size 12 shoes. I'm gonna make sure he is aware of where to put those big feet when braking. You may have saved me an accident.

Hmmm, maybe a bad throttle position sensor?

I had a shop mechanic drive my VX through toolboxes and the cinder-block wall in his bay last year because of something similar (I heard it happen but didn't see and the sound alone was painful). He tried to blame my brakes but the fact is, his big old work boots caught both pedals and the more he thought he was stomping the brake, the more gas he gave it.

Needless to say, I had the brakes looked at when she was in the body shop (their treat of course), and there were no brake issues. Still, almost $4k in damages.

WORMGOD--- Damn, that's absolutely terrible to hear. I remember when I first took my newly purchased eBay VX into my local ISUZU authorized GM dealer for its initial mechanical evaluation. I specifically told the service write-up rep & the actual service technician to be extremely careful of the gas/brake pedal proximity, as I had just experienced the scary "double-foot" incident. It was a good thing I did, because they had never saw a VX before in their shop, and it's quite easily possible my VX could have suffered just as yours did.

Yeah, I had to remove my custom gas peddle for that same problem. On the way back from the 2008 Moab trip I let Eric the friend that went with me to Moab drive the last stretch on the way home. He stopped at an intersection in Price for a red light. It was late at night and there was no traffic any where. Well just as he was about to stop he started slowly creeping in to the intersection. The look on his face was classic. It was like he was getting ready to say,”I think you’re gonna need a Bigger Boat.” I now what the problem was because I’d done it myself. Well, about a car length in to the intersection I lean over to him and say. “Your foot’s on both peddles.” To this day I still give him crap about that.

I took it to the dealer. they checked it out and said that it needed the gaskets replaced. and the injection tube was stuffed with carbon. They tell me they have seen this problem with this engine. now that the top end has been cleaned and gaskets replaced. it runs like a champ and the idle is smooth as can be. it apparently had never been done, as they said it was as bad as they have seen. anyway you were right big swede. with me. i was completly stopped and had been for about 20 seconds. waiting on a light, when this happen. in my case it was not big feet or wrong pedals. anyway an expensive lesson. all is well at this point and i thank you for your comments. satch

[Satch]

I got it fixed it was bad manifold gaskets. Big Swede you were right on the money. also the tube was filled with carbon and had never been cleaned. now it seems to run just fine and i will keep my fingers crossed. don't want to buy anymore bumpers.. thanks. Satch.
