OK fellas, the Disco is running pretty well, but the idle won't even out, seems to be surging, but I can't tell if it is electrical (thank you Lord Lucas), mechanical (vacuum leak?), or hydraulic (bad injector on one or two cylinders).
I have replaced the coolant temp sensor and the battery, and even cleaned the dreaded K&N air filter. The truck starts up perfectly and almost immediately begins this low RPM surging...
Damned thing runs fine, gets me to/ from work every day (100 miles), the gas mileage seems to be coming aorund too and I'll have new oxygen sensors soon (I don't know why I think I need to replace them, they only have 163K on them and they LOOK fine
.
The surging reminds me of a Toyota without a full radiator and the ECU can't tell if it should be in cold mode or hot mode...
Oh yeah, I put a new cap/rotor on it last week at about 44K on the old cap/rotor. Maybe try some new plugs this weekend, the weather is supposed to go positive in temps.
Peace,
Paul
