When my truck is cold, no problem. When Truck warms all the way up, and I stop at traffic light, I watch oil pressure fall on gauge. I raise idle, oil pressure goes back up. This doesn't happen when moving, only at idle. Have done the kerosene treatment to clean sump, can not afford to have engine removed to clean; no more goop coming out. Have replaced IAC vavle. The idle doesn't drop, oil pressure does. Sending unit for gauge replaced. Mechanic tested pump with mechanical gauge and pump is working. I live in Florida, have now got a less than 10 mile radius to drive, This is scary. Any ideas? I do not have money to throw at this.
have the same problem?
