Engine Mechanical problem
1998 Chevy Truck V8 Four Wheel Drive Automatic 144, 00 miles
Hello, I have had this truck for 5 years with no problem. A friend borrowed truck to haul equipment 1000 miles away. When he brought it back, he said it will not idle and would barely stay running. (Nice friend). So here I am with a problem. I changed all plugs, wires and rotor. Flushed radiator, changed oil, oil filter, new power steering fluid, new brake fluid, and cleaned air filter. I pulled off intake and sprayed carb cleaner. I added marvel mystery to gas and filled tank up. With all that being done, it still has a rough idle around 400 on RPM gauge. Oil gauge fluctuates around 40. Headlights are dim, but when accelerator is pressed they go bright again. I definitely here a ticking under the hood. Fuel module in gas tank was replaced around 6000 miles ago. I also replaced the fuel filter about a month ago. Please help, I am confused. Could it be IAC, MAF or what?
have the same problem?
