okay, i've got an issue where when my car is parked outside all night, it won't spool up properly when i drive it in the morning on my way to work. it does this thing where if i apply enough throttle to get close to 0 psi, the car bucks back and forth like a fuel cut off is occurring. only after driving for a good 10 minutes around town (sometimes longer) will it then spool up and boost as i apply the throttle. i'm predicting it has something to do with the air temperature or something, because my car spools up fine when i drive home after work (my company's garage is underground and heated). any ideas? the check engline light almost immediately comes on when i start it in the morning, but never when i start it to go home after work.

 

Search about pulling CEL Codes, and do it when the car is COLD!!

 

well the CEL still kicks on eventually after driving for a while and then when i come to a stop, it's because of the EGR valve (i have aftermarket intakes), this was confirmed by the shop that inspected the car before a i bought it. they said it wasn't an issue and that the only way to do it would be to disable the EGR or put hte stock air box back in.

 

i had this problem 6 ys ago glad u fixd it

 

Your car should have a double throttle system that prevents hard boost when it's cold.

Also, the bucking sounds like 3k hesitation. Run a search on that subject and see if other peoples descriptions match your symptoms. The only true cure for the 3k hesitation is an aftermarket ECU like a PFC.
