Q: Engine

asked by on

When I give the truck gas and rpms go above 2000 the gage drops and the truck tires to die I have replaced the map sensor, iac, tps, cap, plugs and wires nothing has helped and has new coil

My car has 260000 miles.
My car has an automatic transmission.

It’s quite possible that your source to this problem is rather simple; such as fuel injectors or the throttle body that is clogged with excessive carbon deposits. I would start by cleaning these components and seeing if it clears up the issue you’re experiencing. If this doesn’t help, contact a mobile mechanic and have them complete a car starts then dies inspection.
