Problem when Switching My EK on

[RUDEF2]

I have a Problem when I turn the car on....

First off all, I turn the car on revs come up to about 1000PRM then it suddenly drops to about 350RPM then goes back up 1000RPM, I think there is something wrong with my baby

Note could it be my air intake sensor, as I have a Chip installed to make the air intake run at 0 degrees...

please any suggestions

Or possibly the fuel regulator?

My engine light is on constance and so is my SRS :(

Is it only when its cold?

something sorta similar happened when i had a small air leak? it would go up to 1kPRM othen drop - it would do that afew times ....

not sure if you might have the same problem... maybe damage air or map sensor???

[RUDEF2]

It happens every time i turn it on, cold, warm etc it could be the map sensor mite take out the air intake chip and see if that is the problem, but there is like a hissing sound coming from the engine mite be a air leak in my vacum line???

vacuum leaks are real bad, they can change the mixtures and cause the engine to hunt

1st read the fault cods from the ecu
then replace the chip with the stok one. then try it
