So it all started when my dad moved my car out of the garage, I was at work so I dont know if he drove it around since he never drove a turbo AWD car:D... When I got home the alternator belt was all ripped, part of it was still there. now it feels like its shaking like crazy, it almost soulds like its out of time. My friend thinks it could either be a fuel problem or the belt jumped a tooth. I changed the spark plugs and they all get spark, the car idles but as soon as you hit the gas it wants to die:notgood:.. I didnt really get to check everything but I will tomorrow. My friend is gonna see if the car is even timed because it ran fine until my dad touched it....
 
timing belt and while ## down there check the balance shaft belt that'll cause a vibration once your under way.
 
Well back at square one. Last night i checked my timing an everything lined right up fine. So now timing it out:confused:. I'm now thinking its a fuel problem. Because when the kid i bought the talon off of. When he got it,It had a fuel problem. The problem was there was no injector seals. So we think its back to fuel problem. Mabey a pluged fuel filter or line or a bad fuel pump. Tonight we will find out. If anyone has any ideas it would be great to hear them:thumb:.
 
I would check around the MAF and any intake connections. A boost leak test would probably be good idea also.

I agree. A boost leak test will help determine why the car wants to choke and sputter when you hit the gas. Is this what it does? The car can idle almost OK with a lean A/F ratio but as soon as you hit the gas it will sputter and crap. Its like having a hacked airflow sensor and not correcting for it with the AFC. Do you have a datalogger yet? It will be the best $100 you spend! :cool: Is your BOV recirculated or vented?

Thats whats its doing. A/F gauge reads lean just like your saying. I dont have a datalogger eveything is still stock on it. It still has the plastic BOV.

Is your airflow sensor hacked? Do you have an AFC or a way of controlling your injector duty cycles? You have a leak after the MAS but before the intercooler somewhere. This may sound funny to some other people but how does the 2g stock boost gauge act when you have a boost leak at idle? Yes, the pipes are always pressurized at idle, maybe only 2-3 psi but its still boost. Does the gauge read pretty close to vacuum at idle or move at all?

The AFR gauge is hooked up to the blue wire coming off the O2 sensor. When the car idles it reads vacum not boost. An the BOV is recirculated
 
Well we figured it out. My injectors were clogged it had this junk in it. It looked like saw dust but a liquid ha. We cleaned the stock ones but. Changed them for stock 1g infectors. It now runs perfect no spitting or nothing. Thanks eveyone for the help:thumb:

I had a feeling it was a fuel problem since the gauge was reading lean as:shhh:.. glad to hear the car is now running fine and smooth;)
