Did you do a voltage drop test on the feed and ground side of the charging system circuit?_x000D_

I will check that outI have checked all that and all checked out good. I actually cleaned the IAC about 2 months ago because it was full of carbon build up. And no check engine light.
Quoted From college man:
take a look at your IAC try tapping on it with the handle of a screw driver to see
if the idle changes. if it does replace the IAC.also check the tension on your throttle
cable.Any check engine lights on? if so post codeshttp://www.youtube.com/watch?v=L788jKEV … plpp_video
I will check it out this Friday. I found a wire that was cut off or was pulled from the left kick panel. It looks like its the ground to something? Sunroof maybe?

Here’s a video of the RPM’s..Sorry about the bad angles 🙂
Alright so we never found out what’s wrong with it. The car only turns on in a different firing order. We put them as they should be which is 12 in the bottom and 34 on the top and it sounds like it wants to turn on but it just doesn’t. My bud said he’s going to have to take it to his shop because the heads of the motor are different. He said getting the timing on it will be hard as well since it has double gears. Could it be a bent valve?
Quoted From hbvx:
Ignition misfire?
Don’t those Si’s without tweaking require premium gas, etc? If OE required platinum or called for them in replacement I’d go platinum NGK, but I’ve never owned an Si so not sure how sensitive it is to backfiring on ‘wrong’ plugs.
That backfire though…if its not ignition I suppose a worst case scenario is a bent exhaust value. Did you ask your friend how far out of time it was? Not sure if a bent exhaust valve would cause backfiring, just thoughts after the timing was off and for who knows how long it started skipping teeth until timing got to where it wasn’t in a startup state.
The type of gas I put is unleaded. On the gas door theres a sticker that says “Use only Premium Unleaded” Not sure if it means Premium type gas or Unleaded. And I will check the manual today to see what spark plugs go in because the ones that were in there were platinums. The timing was not far I think it only skipped 2 teeth from the looks of it.
Quoted From college man:
what gage is telling you its lean. if it is lean its vacuum related or fuel. did your friend put a timing light on it? if so what was the mechanical timing. C8-)
In the video I posted up you can see. It’s a gauge that was installed. And no he hasn’t put a timing light to it. He will be coming tommorow to fix the problem and to fix the problem with the car fan not working.
Alright so my bud got the car running now. But for some reason when im in first gear and step on it theres a loud popping sound that comes from the muffler. And when I try and start it for some reason it sounds like it barely wants to start. And I also saw that it shakes alot when I step on the gas a little. It also shakes a lot once the a/c fan comes on. Heres a video. http://www.youtube.com/watch?v=k9DiE5TpJks
I have no idea what he did but he aligned everything back up. Just right now I took it out for a test drive and it drove good till 3rd gear that’s where the muffler started making the popping noise. I stepped on the gas and it just didn’t want to run anymore so I drove it back home with the gear in 1st. I have no idea what’s wrong with it. On my gauge it says that air fuel is lean. Not sure what that means.
Heres a video of the car starting. http://www.youtube.com/watch?v=uC2nqo6xC58
Could it be the spark plugs? The ones that were in were platinum’s and the new ones I put in are NGK Standard Copper.
