    F20B swap problem...

    Hi!

    I have finished my F20B swap like 10minutes ago
    But, when I started it, it went up to 3000rpm, and just stayed there
    Any idea what it could be?
    Not getting any CELs btw...

        Sounds like a TPS or O2 sensor.. that's the problem I'm having with my car right now, its idling all over the place and runs like crap right now

          If it's a bouncing idle, clean your FITV and throttle body. The screw on the throttle body is also good for adjusting the idle, but some people recommend against touching that. It worked for me, but I was very careful with it.


          I don't believe a TPS or o2 sensor would cause a bouncing idle. However, they're both replaced easily enough. DO NOT get a cheap replacement o2 sensor. Get OEM only. Bosch and other autoparts store replacement parts never seem to work right on our cars. As for the TPS sensor, those things that appear to be rivets are just headless screws. Use a hacksaw to cut a slot in them, and they'll back out with a flathead screwdriver. You'll need to properly calibrate the new sensor, though... I believe there's a writeup on that here.

          However, I doubt those things are causing your problem. They're both smart things to replace anyway, however.

            I used the intake mani from my old H22A, and everything worked fine when it was on that engine...
            If the thermostat is broken, how will I know?
            And, will it affect the idle...

              If you have a question about the thermostat... just replace it. They're dirt cheap. Again, something that's good to replace anyway!

              The thermostat wouldn't cause a bouncing idle, as far as I know. The only thing it would do is cause your car to idle as if it were always at one temperature... which, if read as cold, would possibly keep the RPM high (though the o2 sensor usually kicks into open loop when it gets to operating temp, which is usually what brings the idle down.




              Also, don't forget... what worked on the h22 won't necessarily work on the F20B. It's a different engine, with different breathing requirements. The fact that it's set up for the h22 may be exactly what the problem is.

              Clean the IACV and throttle body first.

              If that doesn't work, adjust the screw VERY slowly and carefully. Small turn, wait, goose the gas a little, and see where it settles. The surging should go away gradually, until it totally stops.

                I discovered one more thing, when I let the car run today, still jumped from 1000 to 1800rpm, the fan doesnt kick in
                So I had to stop it before it over heated....
                Any idea what causes this, and, will it affect my idling?
                Appreciate all answers

                    I used a stock P13 at first, but switched to my chipped P28, adjusted the idle, and now it seems to be fine
                    But my fan doesnt come on, and the car isnt overheating...
                    Going to change the fan switch and see if that helps.
                    Fan is working btw...

                      That is the LAST and when I mean last the LAST thing you touch adjusting idle. It could be as simple as something like a vac leak or a hose disconnected. But NEVER touch the idle screw unless all other methods have been resolved.

                        .

                        I did search for leaks, but couldnt find any...
                        I also tried to clean my IACV, but that didnt work either...
                        But if there were a leak, wouldnt the idle keep bouncing after I adjusted it
                        Appreciate all tips
