Rough idol after idling long period ,but smooth's out after cooling off, until another extended idol period.is it a coil breaking down


I don't know year--make--model? The basics for a rough idle is to check for a leak of some kind, fuel--egr--vacuum leak, something of that nature.

Any applicable trouble codes? Also, check and clean the idle air system, see if it helps?

Ignition timing 1988 subaru 1.8l


the timing at the distributor is 20 degrees before top dead center. Also check your fire order 100 times It CAN start and run funny with the fire order off. She fires 1 3 2 4 (left head then right head) and your cylinders are clearly labed with raised numbers on the block at each cylinder.

Hope you get her running smooth soon!

The timing is not set right i have a 1996 chrysler concorde lxi what should the timing be set to?


If I remember correctly it is roughly 12 degrees before TDC. I usually set them between 8 and 12 degrees on most vehicles always at least 8 degrees but no more than 12 degrees. If the engine keeps running roughly after you turn the ignition off cut the timing back if it is idling smooth and does not hesitate when you give it gas you are most likely in the correct range.

TRUCK DIED WHILE DRIVING


If you felt a loss of power, you had to press on the gas harder before it died, you may want to check on the fuel filter.  Otherwise you may want to check on the fast idle valve or pcv if it needs cleaning, or vacuum hoses if they have leaks which may be the cause of the rough idle if its an EFI engine.
