Hi guys, i have checked my vaccumes all fine, i have check the leaks there are no leaks, i have checked the turbo controls from primary and secondary and every thing seems to be working perfectly fine, the problem arises when i floor my car as soon as i do that lets say in 1st gear my boost will kick in but then the car would start to hesitate very badly at around 2500 rpm if i let go of the pedal and lets say it pressed 25% of the way the car would go but not hesiatate but as soon as i would floor more than that the car would hesitate and then at around 4500 mark all boost is gone and the rpm would go up very slowly as if there was no compression in the engine (i have cheked the compression also) and as soon as i let go the padel completly the car would give loud bangs from the exhaust and when the car hesitates there is a lot of fuel smell in the car, i have no clue what is the problem with the car if any one ca please help me out i am really confused.

Have you looked under the car and checked if perhaps one of the turbo actuator arms have bolted off?

i have checked that also even they are in place every thing in in working order

Sounds like the engine might not burning all of the gas going in. Check the plugs and coils. Not getting enough spark would be my guess.

Is the car running on the stock efi system? You say it's a boost issue but made no mention of any boost problems from what I read.

Try cleaning your injectors. My friend's primarys were very dirty, and when he hit 0psi, his car would hesitate for a sec or 2 until his secondrys kicked in.

After years of driving- your cats can get clogged causing backup, during spirited driving. Good excuse to go single............

Hi,



Have the same problem you've got. Have you fixed it or found the cause of the hesitation???



I checked the a/f cos it seems that its running lean... what do you think???

my car had a similar problem exept the primary turbo would boost and not the second, had a cloged cat and a stuck open charge control valve. bypass vales go out like nothing too
