Hey guys, I'm new here driving Wira 1.5 AT.
My TB got a bit of a problem right now. My mechanic said that it got problem with sensor or what and now it is like useless. He mod it so that the car still can be drive but not sure how long it will last.
So the current condition is, during idle, if a/c off, the timing will go up and down, a bit jerking and exhaust sounded like poof poof. If a/c on, no problem. This is how my mechanic mod it.
Ur engine injection or carburator system.....if injection, old model(mitsubishi) or new model(siemen VDO).
If mitsubishi injection model, my guess, ur foreman has install FICD to stabalize the idle, but still the idle will happen like ur said...only normal when your on your acc.....
My guess only....
Just my 10 cents..
Lot of improve to everybody....Happy New Year to All.....
