I just fixed the rough idle and stalling; which was the IACV and map sensor connectors switched around. Road tested it and it drove great..parked it started it up again as soon as i boosted at 4g the car just jerked (fuel was cut) and when i stopped at a light rolling off again in 1st the car would jerk hesterically..not everytime though.
if car is driven conservatively there is no problems....any ideas?

 

Could be MAP sensor related, are you running the ESM box from COmptech?
Make sure its at the right voltage of 2.93V for the CLS 6spd) I think 2.83 for everything else except the NSX.

Check the wiring of the box too, to make sure its still intact.

 

In another thread, he said hes getting 2.84v...

 

wasn't it 2.84 for the CL-S 6? i dont know, i rechecked the ESM wiring it was alright; i soldered them earlier also...

any ideas guys? im just so anxious to get behind the wheel and drive it again...i straightened out the other problems now there is another one....

sigH*

 

set voltage to 2.93 still cutting, car idles fine and revvs fine in neutral. will dirve fine until i get the the throttle...more then 1/4

 

If it runs fine under light throttle, I would take another look at the ESM wiring. If the ESM isn't doing it's job, the ECU would see boost and it's not supposed to.

 

Yeah i've seen the same timing retardation on SIRSIG's car when the Greddy Emanage would no longer hold the MAP voltage and the ECU would see boost causing a great amount of power loss.

So any CEL's on?

 

Not even power loss; the motor just stops you from going anywhere under load....
it would rev freely in neutral...
Comptech sent me a new ESM which i wired up..problem persisted

I disconnected supercharger belt; same thing
reinstalled stock FPR and Fuel pump; same thing

I'm fresh out of ideas...
the car was running great for the first 5 minutes after install...now it just cuts when i push on the throttle...but idles great and revs great in neutral.....any ideas guys!? thanks..

and no check engine light...i wish there was...
