Ok i just bought the $8 Ultimate Car wash and i'm sitting there listening to music waiting for it to finish when my engine starts sputtering. I shut it off, turned it back on, same thing. I leave the car wash, and there's delay in the gas pedal, and keeps sputtering. I get up to 55, it shifts into 4th gear and starts vibrating. I shift back into 3rd, its fine, shift into 4th and starts vibrating again.I stop at the stoplight and its still sputtering around 400-500 rpms. I let it sit for about half an hour, go back and start it up again. It starts fine, but after about 10 seconds, its idleing at 600rpms like normal, but is still sputtering a little.....it sounds like i have something wrong with my TPS...but i'm not sure..what the heck is wrong???

 

You got water in your wires or cap, happens to me usually when I get the underbody wash. Take it off and try to dry it out I guess. Mine usually just fix's itself

 

Thanks for the reply so quickly, that sounds like it could be it...its happened to me before when in the car wash. I'm letting it sit right now to dry out, so hopefully it will work alright.

 

Yeah, I agree w/ Socha_62 it's probably the distributor cap got water in it.
Let it dry and you'll be up and runnin.
If itstill doin it holler back some one in here might have another idea.
