Engine dies when hot, in gear

The "empty" filter is actually full of pressurized fuel vapors.

Have you checked your fuel pump? ( Doubt that is the issue)

Have you checked your fuel pressure? (Cold and hot and when having issues)

You can try an easy thing.

Go to www.pure-gas.org and see if there is a station near enough to you that sells alcohol free gas.

Run your tank down to 1/8 tank and fill with alcohol free gas.

See if you still have the issues.


This is my dart on standard pump gas with typical alcohol.

During this test. The pressure between the filter and the carb stayed at about 5 to 6 till the filter was fully empty, the pressure lowered to about 3 then the engine rpm started to drop, then the inrush of fuel and the rpm picked back up. This would happen when ideling after a 45 minute around town drive.

On really hot days (90+ deg) if I sat in a drive through lane then hit the road. Under normal acceleration the engine would loose power, I would let off the gas the engine would return and I could keep driving.

ALL of these things went away when I started using alcohol free gas, NO OTHER CHANGES!

don't know if it will solve your problem but it is easy to try.
