Update
It happened again last week. Engine stalled when put into gear D or R (note - I do not have problem stalling while driving or comming to a stop)
Whenever it dies when shift into gear D or R, I also notice little rough idle and if i give it a little gas, engine would stalls out. Now, if I let it runs for few minutes until the idle smooth out, then engine will not stall when shift into gear D or R.
I also have couple other problems that may or may not be related.
1. Sometime engine stalls immediately after it starts.
2. High idle (1000RPM) when gear in P or N. 700RPM when in D or R.
I decided to have the pro check it out instead because I am tired of this guessing game. I just want to solve it quickly and sleep in peace instead of monkey around with it until I get it right. I also don't want to be stranded on the road down the line.
Before I brought it to the indy shop. I replaced the fuel pump relay and still stalls when shifts into gear D or R.
Here is the diagnostic from my indy shop for the problems
1. Engine stalls immediately after starts
2. High idle
3. Sometime engine stalls when shift into D or R.
Indy - Checked fuel pressure and tested idle control system. Indy recommended replacing idle control unit, idle control valve (sometime sticking) and overload protection relay.
I have all those stuff from a part out car except for the OVP so the indy replaced the OVP. I will clean out the ICV and replace the idle control unit and see what will happen.
I will report back to let you know what I find. Hope someone with the similar problem will find this thread helpful in the future.
