I believe you can buy just the tps alone at honda parts department. some cars are attached to the t.b. but most of them are seperate.

do you know how much it is roughly ? thanks

i've got da exactly same problem with my ek4..i was just told to replace the air control valve...which i think costs about 200 bucks.

just because you cleaned yor IACV doenst mean its all fixed and its working like its ment to.

try getting another IACV from another car to test to see if that is the problem

make sure your TB butterfly is clean

had a similar problem in my ek4, replaced the battery and all was fine.

This may sound stupid but have you set your base idle?

[nugget666]

hmm have you been playinfg with your "idle screw" You could of played with the wrong one. ( cant rmemeber what the other one is called) but my mate did it to his car and it was reving up and down.

Have you tried a tuneup first? there are alot of things that can affect your idle. My last problem was spark plugs. Less than 5,000km platinum plug.
Somehow one just died.
maybe your timing is out of wack?

[anfz]

well i havent played with any settings idle or etc,I have changed my battery not long ago when my alarm stuffed up on me so its not that ? ill try out the ones mention so far maybe clean out the iacv one more time more in depth,Ive been told it could be this one hose that has to have coolant going through and make sure thats not blocked .
