so my car threw me some codes today,wasnt the first time it has happened. it used to do it only on cold days untill it warmed up and then the light went off. but now its doing it everytime i start the car for the first time that day, light comes on, and while light is on the car seems to have alot more hesitation and kinda chuggy feeling, but after the light goes off it runs like normal and if i start it up any other time of the day it runs just fine.i dont get it. i read the codes and got: 22 knock sensor, 23 Air flow sensor,24 Air control valve and 45 Pressure sensor and pressure exchange solenoid valve.

i was wondering if anyone could give me a rough estimate of how much its gonna cost my bank account to replace these?

thanks

Have you cleared the codes and seen what comes back?

More then likely it is the knock sensor. They get old, the plastic cracks, and shorts. There is a new design, and run about $60 I think.

ok.is there a thread about how to do that?

My website has that info

oh sweet thanks

i took it in to my buddys dads shop and he was dinkin around with it and he stumbled apon a tube that came off the turbo and went into the block. the tube was cracked pretty bad, so ordering a new tube hopefully this will solve my problems
