FIXED...IT WAS THE INTAKE MAIFOLD GASKET

i have a 94 ex that had a d16 in it ran fine , got a rod knock , so i just finished putting a d15 in using same harness at d16 , all i did was witch over throttle bodys . first time i stared uo it went right up to 4k just stayed htere, now today i added more fluids n stuff , still does it goes up to 4k rpms then goes to 5k all by its self. i checks for vacumm leak only thhing i can think about is intake manifold gasket, even it i plug up the 2 hols on throttle body its still high, also would like to know the firing order , im still using d16 ecu wiring and dizzy

no one!@1

 

Firing order :::

4321 is how its numbered

so its like this on dizzy

34
12

 

ok the firing order is good now , i tried to put my hand over there tb and still does it , so idk if the intake manifold gasket or wat , if tps is bad will it casue to go up thaty high??

 

Any CELS?

 

yeah for 02 sensor but it didnt do it before with that cel , and its a auto ecu ..ill douoble check tomarrow

 

Iv heard of this happening with a k swap but it was because it still needed tuned

 

check the butterflys in the TB might have something stuck in there holding them open.. thats what mine did when somethign was stuck in there

 

tb is fully closed trsut me

 

is your throttle cable adjusted? thats seems a little high rev with throttle closed.
just my 2 cents

 

yes trust me its all good with throttle

 

bump

 

Switched the IACV and TPS sensor? or whatever ones are the same...

then ur car shouldnt rev, no air = no power.

thats menas my intake manifold gaskect is gone..trust me i put my hand over it and just reved up lol , any one else

 

spray carb cleaner around where the throttle body and intake manifold meet, if it bogs down you found your leak. if not then spray where the intake manifold and head meet.

2nd that. check the iacv. if theres a leak there, the motor will rev up.

 

Pull off the brake booster line & plug the nipple, then the PCV tube & plug that nipple. It would be my guess that one of the two are shot & leaking lots of air.

One thing to try is to get a can of CO2 or something like ether. Spray it around possible problem areas, and if it revs more or slows, thats the problem spot.

 

some good i deas guys ima try all this today

 

sounds like intake gasket or throttle body gasket. the iac valve would not allow a 5k idle lol

 

I had this happen to a d15b swapped crx of mine. Though mine was only revving to like 2 or 3k. I know this isn't an ideal solution but what I did was just disconnect the TPS sensor. After I did that it stopped. You could try that, then if it stops you have at least found your problem. Then just go purchase a new sensor.

 

i tryed doign that stil up at 4k or so

 

Air is getting in somewhere, go and find out where.

 

ok i compltely blocked off the throttle body , and it started up some how....im thinking is something electrical , maybe d16 ecu and dizzy not gonna work right
