I have a automatic jdm p13 that was reprograqmmed into a 5-speed . I have pulled the codes and no-codes I have fixed all the codes in which the computer has told me to fix. On the other hand still idling badly and car shudders and i get an up and down idle from 1,500 -1000 rps when I start it up in the morning.

When my car warms up in the morning it does the same thing over and over again im stumped . Guys please help me out I have changed the idle air control,I have changed the tps sensor,I have checked for leaks nothing no bubbles. Nothing at all seems to cure it my timing is set everything.

the only thing I have not tried yet is changing my fast idle thermal valve they whinded the circle thing back and it stopped for a while. Now still with the idle prob.
This is the worst thing in my life when it comes to cars yo I wish I had some help not even the local swap shops wanna fix or investigate always sayin their too busy.
Once I mentioned the word prelude swap the go nuts like they seen a ghost.

On top of this whole thing will the computer I have mentioned earlier before cause a bad idle and poor drivalbility cause v-tec comes on and everything but when I run the car had it does this. and im not sure but it my red-line at 8000rpms? cause I changed the fuel pump and all man this sucks

 

Well if i could see some periods or maybe some structure I could understand this and answer your problem but all i see is your paragraphs going and going and by the time i got done I had already forgot the first sentence.


My advice is to find a real, non-chipped ecu for your year and model prelude. Then plug it in and see if it works,

and pay attention in english class.

 

I put my f22 back in there still the same thing? now what do I do? plus I have no codes and the bulb works thankyou very much? Now what do I do?
