I had a 95 si vtech motor in my hatchback and I blew up my pistons, and now i just swapped my old dx motor back in, but the car is revving high at idle, it's revving at about 1500 rpm, i changed the ecu and adjusted the throttle. But i'm stiill having problems. ITs not running well too. When you try driving it, it drives a little bit and then dies out. Please email me at femosticos@yahoo.com, or send a reply if you know what the problem might be.

 

i'm amazed that you blew up your pistons!

i beat the crap outa my car & have yet to blow up a piston.. i'll keep tryin tho!


as far as your engine dies out.. i'd have to say u should be throwing a code for this.. i doubt the IACV would do this coz when it goes it normally just idles up & down but doesn't stall on ya. So i would have to say check for good compression & spark on each cylinder & make sure your throttle is adjusted properly. If your timing is off really far i guess this could cause it as well but the thing is, we don't have enough info here to pin point the problem. Go ahead & check for codes & see what ya get.

 

check for vaccum leaks and make sure you plugged all the sensors where they belong
