New car Problems, Preparing to take on a new Evolution Options

[mitsu90]

Got all the bad gas out of the new AWD. It is now running 110 octane. Changed the injectors and that helped smooth it out some.

Some of the problems now....will not rev past 6300 and takes a while to get there. It does not bounce off of a rev limiter it just won't go any higher......there is a loud POP coming from somewhere under the hood, can't tell if it is coming from near the intake or the IC. It you can feel it through the UICP and the sound seems to move.

You have to hold the gas to the floor for it to start. We were thinking maybe bad fuel pump and/or filters???

When it does idle it sounds fine except for a hiccup every now and then that almost sounds like when your A/C kicks on. When you try to drive it you have to floor the gas and it seems to have no power and wants to go nowhere. Possible boost leak?

Things we need.......Timing Belt (looks like swiss cheese), logger, and somebody with a little more knowledge.........Nate, Marcus, Kris

If you have high miles, i would replace the tensioner pully and idler pully for some insurance. You can get them on machv for like 20-30 bucks each.

Ive done 3 timing belts, and i bought all mine through oreillys for like 45 bucks and havent had any problems. But most do recommend going OEM, im not sure how much they run at the dealer
