Re: resetting ecu + gas problems

To reset your ECU just dis connect the battery for about 30 mins then hook it back up should be reset, will also be pretty rough to drive for a bit, but will get better as you drive it more.

Re: resetting ecu + gas problems

Sounds like an IAC issue, don't disconnect the battery it may run worse. Give the throttle body & IAC motor a clean first & see how it goes. If you know how also do a base idle reset.

Re: resetting ecu + gas problems

like what info?

-> it idles at 100rpm on both gas and petrol
-> once i stop at lights it stalls 1/10 times by the needle geeting to 0
-> sometimes once it gets to 0 the engine revs by it's self and takes it to 1500 rpm then it comes back down to 100prm
-> it has problems starting on gas so i need to switch it to ulp and start it up
-> if i manage to start it on gas it drives like shit and accelerates poorly
-> gas was tuned up 1 week ago thats where the gas problem started didn;t affect the idle that was a peroblem since i got the car

enough information?

Re: resetting ecu + gas problems

Chances are that the gas "tune" was done when the car was warm, many, ( poss more than 60%) of dual fuel systems are designed to start on petrol and then switch to gas, esp. when cold.

If you had it tuned a week ago I would be going back and asking for an adjustment,

If the problem is warm start then the same applies, the tune was not done properly.

Regards Prof. Rabbit

Re: resetting ecu + gas problems

The throttle body is what the black flexible rubber hose runs to from the air cleaner box. The IAC sits on top of the throttle body, it has 2 10mm headed bols securing it.
