Please help..not spark or main relay but seems fuel problem. Only occurs after 60-80 minutes of freeway driving on first slowdown where rpm's drop below 1800 on lifting gas pedal. It will start back up but have to keep rev's high to keep it going (at worst) or will stall at 1st stop light (at best). Also happens after long use on hot days. After letting cool for an hour seems OK till gets hot again. Replaced Fuel filter, main relay and think ICM is OK..again it has spark. I have heard Catalytic converter? Pinched fuel line? Out of guesses. I was stuck trying to get home once and sprayed water on the fuel rail to cool and that worked...but next time did not? Now also intermitantly hesitates on acceleration from stop. Also seems like low end torque low. Any help would be GRATLY appreciated.
