The problem is the idle is very rough, the alignment marks of timing on crank and the cams are correct...
the car almost times have a failure like a problems with the gas... but if i push the accelerator to the bottom, the car make a hit/jump and the PSI come up.. and runs fine.. if i deaccelerate, the fail back... and the psi of boost drop and the revs up, but the car dont keep moving :(

this problem begin the day in i was istalling my turbo kit... this day the turbo make contact with the + terminal of the starter and with the power steering bracket.. but all the fuses are ok..the car before of that... ran like a champion!! :(

i scanned many times and only have this codes:
p0505 "Idle air control motor circuit"
p1294 "Target idle not reached (k200 r/min)"

thaks guy i hope in yours can help me :(
rettez.

Check the IAC plug and wiring and make sure you didnt leave it unplugged or that you didnt damage the wiring.

good advice also check your map sensor and map "missing link" if you have it...

IAC codes have nothing to do with Map sensor!

Pull the connector off of the idle air control motor (the bottom sensor on the throttle body) and get a multimeter that measures ohms (most do) and put one pin of the multimeter on the 1 and 4 pins on the Idle air control motor and then on the 2 and 3 pins on the motor. Both should read between 38 and 52or53 ohms of resistance. Most that i have measured have all been about 52.5 or so. If the motor is bad, it will not idle right, which also may be throwing the code for engine idle not reached (correct me if i am wrong, just makes sense to me) The IAC's are kind of expensive at autozone, but i got mine from rockauto.com. They are very cheap and you can find almost anything on there for any car. They basically sell you parts at a little more than what they pay to get them. I believe i paid about 40 bucks for mine, maybe 50 shipped, can't remember, but much cheaper than autozone, as they are 80-90 and over 100 at the dealer. It fixed my problem, so i thought i'd throw in my 2 cents.
