I have Alfa Romeo 156 2.0 JTS (Facelift, 2004, Manual).
I have two problems.
1.When pressing on accelerator(while engine is running idle) the response is kinda delayed.
lets say, You press the pedal and the revs respond half a second after it.
2.When the engine is hot (temperature higher than 70C) it does not returns to idle revs (around 800RPM) if throttle pedal is not pressed and car is not standing.
I will explain myself (will try with my Bad English). Lets say, you are approaching red traffic light. So you braking (using the gear or not) and when you are on neutral gear but still braking the engine goes to low revs, but stops for a couple of seconds (or until you stop completely) on around 1500 RPM.
So, maybe somebody can explain me this weird behaviour?
Thanks a Lot.
Have A Nice Day :-)
PS: I have one more question: My engine is overheating a little (if AC is of). It heats up to 110C. But if AC is on holds 90C degrees.
