Can't get the codes..my friend lent it to a buddy
Expert:  john aka eaut replied 1 year ago.

do you have a autozone near you?

Customer: replied 1 year ago.
Po108...po128...po300..po404...p1404..po108..po300
Expert:  john aka eaut replied 1 year ago.

po108 is a map sensor code po128 is a coolant temp sensor issue

po404 is a egr issue the 1404 is also egr

and the po300 is a random multicylinder missfire

are you going to repair yourself?

Customer: replied 1 year ago.
I plan toi
Expert:  john aka eaut replied 1 year ago.

the egr valve map sensr and coolant temp sensor are all likely failed... they are common to fail without a high end scan tool its difficult to test each component.. as for the miss fire I would check the plug wires that were just installed and the ignition coil..99 percent of miss fires are plugs wires or coil

Customer: replied 1 year ago.
I think I'm going to check the senors that screw into the exhaust
Expert:  john aka eaut replied 1 year ago.

the oxygen sensors

? why?

Customer: replied 1 year ago.
Just a feeling
Expert:  john aka eaut replied 1 year ago.

how do you plan on checking them? they have nothing to do with egr or coolant temp

Customer: replied 1 year ago.
Well I had a Mustang that would bog out after driving it for awhile and run like shit..and it was always the sensor coming loose in the exhaust
Customer: replied 1 year ago.
I will also check the plugs and wires again
Expert:  john aka eaut replied 1 year ago.

ok I doubt its the sensor,,
