Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer. Is this the 4.7 V8 engine in your truck?
Ok, does it run ok above idle? And does this engine have the EGR valve on the right front cylinder head?
Ok, thanks. So I am thinking 2 things here based on what you have told me: 1 that EGR valve is sticking open sometimes and causing the EGR to flow at idle which can cause a stall and surging, or 2 the electronic throttle body is acting up. It has a built in TPS that can act up and cause those symptoms.
How many miles on the truck?
Has the EGR ever been replaced?
Ok, then it is probably not that (unless it was a cheap after market one). So I recommend trying a new throttle body. And if it has been a while consider to plugs and wires. There is a date code on the wires. If they are more then oh 7 years old, replace them. I think the throttle body will take care of it though.
Do the throttle body first. If you still have the problem, then replace the throttle body.
Sounds good my friend. I will keep an eye out for your reply.
Very good i will keep an eye out for you tomorrow.
Have a good weekend!
