My LR has 135000 miles on it. It stalls after about 15 minutes of driving. Usually when the outside air temp is below 50 dedrees and sitting at a light. It only does it once or twice then it is ok. It will occasionally hesitate while driving at a steady speed. It restarts immediately. Service engine light came on. I replaced the MAFSand it ran good for several months and started it again. I replaced the crank shaft position sensor to be on the safe side but that did not correct the problem. Any other causes???????

 

Codes? Fuel pressure test?

 

Thanks. Is there a port that I can use to test FP?

 

How about codes? When was it last tuned along with 8 mm silicone plug wires?

 

If a D1 the schraeder valve (tire valve) is on the battery side fuel rail. On a D2 it under the top section of the intake at the firewall/driver's side corner (NAS).
