can a bad tps cause the engine to idle high and sometimes surge? like this is what happens. i start the car it will idle around 1800 and then drop to aroun 600 rpm then surge 600-800 and if im driving then put into nuetral, it will idle around 1800 and do it again.

i checked the tps sensor and it put out a .65volt on closed and at wot 4.9. i tried to move the tps to get it around .5 on closed but it wont so i think i need a new tps sensor.?

i dont think its the tps, sounds more like a vac leak

pull the clip off the iacv and see if it stops. if so, its bad.

my friend's accord did that and it was a temp sensor on the head

uhh the iacvalve is new

like i said on the other forum. did you rest the ecu?

use wd-40 spray around the vacuum hoses, the gaskets, anywhere. if the engine revs up more when you spray the wd-40, there's your leak; if it is a leak.

anyone wanna add anything else to check?

hmm alright ill try all these things tomorrow. im just pissed its happening a month before i got to take it in for emissions lol

thanks for the help

If the IACV is new does the cooling system have an air pocket in it?? I know I had to raise the front of my car up and run it with the rad cap off at temperature and rev it up to release the air.

Have you checked the fast idle valve?

i dont have a fast idle valve. my car is a 96

ok so i checked the tps again this morning and i got it to adjust to .51v on closed throttle and at WOT now only goes 4.56v. which it shouldd be reading close to 5v. so i think i need a new tps... getting the tps voltage to .51 on closed stopped the high idle and pulsing.

Around .5-4.5 should be the range. Sounds like that is good.
