Agreed, on needing more info on the truck. What is it?
Agreed on no ethanol in the gas being better not worse.
My friend is dealing with this idle surge issue as well. He has an EFI Nissan hardbody. Here are the things we have do with no solution....
Changed: Fuel lines
Fuel pump
Fuel filter
TPS
Spark plugs(new ones are already black and we can smell it is running rich)
Checked: Gas quality
Plug wires
Vacuum leaks
Exhaust and intake leaks
Need to check injectors timing and some other sensors.
What causes this? I know most of us or Toyota freaks but the issues and solutions may be similar.
