Ruff Idle (only after turned off for 5-10 miuntes) ? 200

Hello all,

I’m still having a warm idle problem on my 80' 242 but only after the car is turned off for 5-10 minutes.

1) Starts and idles GREAT when it’s cold

2) Starts and idles OK when warm but only if it is restarted immediately after turning motor off.

3) Starts and idles VERY RUFF, shakes and acts like it wants to die when warm if restarted 5-10 minutes after motor has been off. This then clears up after I hit the gas a couple of times. (if I let it sit long enough to get cold it will start and run great.)

Here is a list of items I have replaced new so far:
• Complete tune-up with plugs, cap, rotor & wires.
• Compression check OK
• Flame trap
• Lambda oxygen sensor
• All vacuum hoses
• Fuel injectors
• Fuel filter
• Engine wiring harness
• In-tank fuel pump
• Main fuel pump
• Fuel accumulator
• Checked all fuses

This problem has gotten somewhat better after all the above but is still a major problem.

Anyone have any ideas on where else I can look to solve this problem?

Thanks,
Dale
