I have a 2000, but the engines are basically the same.

I cleaned my TB the other day and now my car is running like crap. I first sprayed into the TB with the car off, then turned it on and sprayed while it was running. I took off my Frankencar intake and sprayed directly into the TB. I had a SES light when I got back in the car. I disconnected the battery for an hour and the light went away. The car has much LESS power now. It will not rev as freely as before. If I accelerate about 1/3 throttle in first gear, you can feel it fall flat at 4300 rpms which I suspect is the point it switches over to the shorter intake runners. Could I have clogged or jammed the assembly that switches the intake runners over to the shorter ones? Did I not reset my ECU for long enough? In resetting my ECU, will I need to drive for some time before it performs well again? I drove about 35 miles today and it is still much less powerfull. The car runs and idles smoothly, but really lacks power in the upper rpms.

1. Check that your MAF is connected
2. Did you spray into the MAF? sounds like some may have got on there.

 

3. Don't post in multiple places....

 

The same happened to me when I forgot to plug the MAF back in. You should always be running better after a successful TB clean.

 

Why not?!?!?!?!

Why only post on the 5th gen forum and possibly miss getting the answer to my question? I am sure many of the 4th gen people do not read the 5th gen posts.

That's why they have a General forum...

Since you unplugged the battery, your ECU might be relearning or something Give it a few days to adjust. Make sure you plugged everything back in tight so you don't have an air leak.

 

there is a general forum, and if its a 5th gen, it goes in the 5th gen forum...
