Dear i know that auto choke kicks in when car is cold... but the problem is that the accelerator pedal don't work like normal... i know that idle speed would be raised till the choke is working but as i press the accelerator it wont come back... increased rpm stays there until the car is hot enough for the choke to disengage... for example if i rev it to 3k rpm when choke is engaged, it would stay there and will not come back to its normal choked rpm of 1.5k... it feels like accelerator is stuck or something... this behavior is not normal in any sense...
