Stephen Posted April 6, 2008 Report Share Posted April 6, 2008 I need some help. My car starts up and idols fine but when I try to take off mainley in reverse it tries to shut off. Once I get going it runs fine or if I leave hard and spin the tires and go through the gears hard it runs fine to, only when I back up or pull off and sometimes when i hit the brakes coming to a stop it will try to shut off. Sitting there idoling I can rev the car up and it does fine and also it does not do it when it is cold only when it warms up. I have tried checking wires under the hood I richined up my fuel mixture at idol and mid throttle. It just acts likesomething is cutting fuel and i cant find it. any info would be most helpful......... thanks Stephen Link to comment Share on other sites More sharing options...
Wolf87Conquest Posted April 6, 2008 Report Share Posted April 6, 2008 Runs fine when cold, acts up when warm...that's the clue. Typical warm run issues seem to be the coolant temp sensor. This sensor is the one straight up on the intake. This is NOT the one for the guage...that one is near the thermostat housing. CTS should have 2 wires...connection clean and tight, might need to be replaced. Link to comment Share on other sites More sharing options...
JAinsworth Posted April 7, 2008 Report Share Posted April 7, 2008 You need an Ohm meter to check the CTS. The specs can be found at this link. It is on page 64. You may also want to read about the error codes and how to check them. A simple $3 led light from Radio Shack works fine.

Stephen Posted April 7, 2008 Author Report Share Posted April 7, 2008 Thanks for the info, I will try that and see what happens. It was just throwing me off because what ever it is , it seems like it is shuting down the injectors for a second then they just come back on, the car never shuts off but comes really close but runs perfect going down the road. i was hoping someone else has had this problom and knew a solution but I guess I couldnt be that lucky. thanks again Link to comment Share on other sites More sharing options...

chasm2530 Posted April 10, 2008 Report Share Posted April 10, 2008 Did you check for codes from the ecu yet? Have you done the tps/isc reset? You'll find the write-ups on these in the FAQ. It would be great to know what your fuel pressure is doing. What's the status of your fuel filters? You can check the in-line cone and the pickup tube "sock" from the access under the spare. If you don't know how old the big filter below the throttle body on the shock tower is-replace it. Most parts stores carry it. Link to comment Share on other sites More sharing options...

Well the fuel filters are new.I dont have the in tank sock or the cone filter because I put in a aftermarket pump and a fuel cell, the inline is not even a year old that i put in when i did the cell so they should be good. I do need to check the codes from the ecu i have not done that yet and I am not sure what the fuel pressure is doing i do not have a gauge on it but it runs perfect under boost so i wouldnt think fuel pressure would be a problom, but thanks for the info.
