1989 Jeep Cherokee 2WD 4.0 liter 180,000 miles
Jeep seems to drive fine but will die upon decelaration after high speeds. If I'm going down the highway, runs great. take an exit and decelerate to stop. Upon stopping, I find the engine is dead. Restarts immediately and runs fine. No check engine light is on. EGR valve sticking, crnk sensor?? Any ideas.

[quote:9bfedb616d="sammy sosa"]my ac is blowing hot air, i got this car from a guy.

1. i put ac belt on it.
2.(i would like to know what is the pressure for the low side and high side) of the ac hose. cause i have a pressure gage, and on the low side is 110 psi and high side in 30.
3. i notice that the compresor is making a loud noise, and the clutch is not engaging.

where should i start? or what is my problem

ps. 1996 acura integra. 1.8l[/quote:9bfedb616d]

Low should be atleast 28-40lbs High 125-160lbs

Put some freon 134a and see what happens

Cranking - 39psi
Idle - 31psi
When I actually drove it with the fuel pressure gauge on the vehicle, I only could make it die out once. When that happened the fuel pressure certainly did not fall substanially. Maybe to 28-29psi at most. Is that enough to make it die? I will try this process some more.

turned out it was the EGR valve. It was sticking open causing the truck to falldead upon deceleration.
