Why is my durango still running bad?

Asked by Claytonpm555 May 10, 2020 at 07:51 AM about the 1999 Dodge Durango SLT 4WD

Question type: Maintenance & Repair

I replaced the tps in my 1999 318 4wd dodge durango and
replaced two injectors and also replaced the spark plugs.
N the check engine light is still on and it doesnt have the
acceleration like it use to and also it will sometimes die
when I put into gear... what's the problem

Clean your map/mav sensor. It's located somewhere on your throttle body/air intake. That little diode measures the amount of O2 in the air and adjusts the amount of fuel to send to the injectors. If it gets just a little dirty it throws off the whole system. Squirt it once or twice with engine cleaner. Be careful though. It's delicate and expensive. It'll improve your mpg too..
