The problem is at low speed coming to a stop the tack will drop to around 500 then surge to 1100-1200 rpm and almost stall.
This all started when the water pump and timing belt was changed. I have changed out the TPS, cam sensor and done a regular tune up with new plugs and wires.
The car has been in the shop and on a scanner with no codes issued. The mechanic did make some adjustments with the scanner and it did run better for a day.
The car runs worse in cold weather. Also when at a stop sometimes the car will idle low at about 600 rpm, but if you put it in neutral then back in drive it will be back to normal at 750.
Can anyone give me a clue on what this problem would be? Any help would be much appreciated.
Thank you in advance Ivan.
