|forsaken82||Disconnected cps cleaned connections and packed with dielectric grease. No sputter on way home... if i was a betting man id bet it will be back but we will see after a longer drive tom.|

|forsaken82||another forum suggested the cps, could this cause it without throwing a code? only code im actually getting is speed sensor which i dont understand since i replaces it already.|
|06-19-2013 12:46 PM|
|forsaken82||Still doing it. Seems to get really bad if I hit a bump while it is doing it.|

checked fuel pressure. its sitting about 52-53psi, bought a temp sensor while i was there. ill let you know if it did anything after i drive home for lunch.
going to the lake camping this weekend so i need to get it fixed.... im gonna hate it if i have to take my charger. its just not the same!

|forsaken82||Gonna check fuel pressure. 45-55 psi right?|
|06-19-2013 07:03 AM|
|forsaken82||I thought fuel pump too but it doesn't do it all the time. Seems to go through spurts.|
|06-19-2013 06:59 AM|
|kik||It sounds like you have a bad/weak fuel pump. You're probably not getting enough fuel pressure under load.|

Plug wires??? You will see them sparking in the dark.
Ecu sets the timing and fuel mixture based on inputs. So the temp sensor or some if your wiring maybe.

|forsaken82||Its just under load. She idles perfect.|

|goatman||Is it at any rpm, or just going down the road, or just idle? Mine sputters around at idle because the TB and IAC are dirty. It has a hard time exactly modulating how much air it is getting at idle so it hunts around. Need to get some carb cleaner and go to town.|

This one right?

The temp sensor is in the t-stat housing, the ECM uses this sensor to make adj to the fuel system. This sensor has two wires to it.
The temp sending unit is what the gauge uses, it is located on the drivers side rear of the engine by the end of the fuel rail kinda under a bundle of wires. This sender only has one wire.

|forsaken82||Wouldn't that cause my gauge to read off too? I assume your talking about the coolant temp sensor|

|Garyk||Check your temp sensor. If ecm thinks engine is cold it will make it run rich..|

bucking sputter at operating temp
I have a 94 4.0 with 160k on it. It sputters,bucks and jumps once it reaches operating temp. So far I have changed tps, o2 sensor, coil, dist cap and rotor button, fresh oil and gas, sea foamed intake, ran a propane torch with no fire over the vac lines with no idle change. Any ideas?
