Ok I thought it was fixed. I put in a new crank sensor started it up it reved up real high I put a new throttle positioning sensor on it reved back down then when I give it gas now it back fires and cuts out so I put the old throttle sensor on but it still cuts out when you give it any gas but it idles great can anyone help thanks

 

ok i let the disco cool off started it up reved up but throttle worked idled down until it warmed up then started cutting out i swapped out ecu coolant sensor but did the same thing. is it possible or does it make a differance if the 2 coolent line to the throttle body were backwards could it cause this.

 

Backwards coolant sensor is not an issue. IACV controls idle air to mix with fuel, but crank position sensor controls timing. Crank sensor can fail when cranking or when running. When you installed, the spacer is important. The fit is bolt heads+spacer+sensor+block. Two version of spacer, on for auto, one for manual tranny. Two wire coolant sensor readings will be seen on a code reader with raw data capability.

 

I understand when I removed the old one there was no spacer how do I know if it needs one and if so what thickness does it need to be and did I mess the new sensor I installed I have only had this disco about 2 months thanks for the help on this

 

I have a 1996 4.0 automatic

Savannah buzz thanks again for the help I did finally get it but I could not get it to idle back down so here is what I did ___ I put spacer and bolt and screwed it about 95% then I put crank positioner on and screwed it in about 95% started it back up with my timing light set to rpm and tightened one a little then the next back and forth till snugged and rpm's at the proper speed. I am sure this is not the proper way but was the only way I could get it to work maybe this will help someone one day but thanks again to everyone
