Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..

try pulling off the air breather hose and look inside at the mass air flow sensor,it looks like a wire with a diode hooked to it incase you didnt know,see if there is any fuzz on it,sometimes the air filter will lose small pieces and the mass air flow sensor catches it.If that doesnt work then you may have a fuel problem,weak pressure,causing the mass air flow sensor to read too much air so it tricks the computer to adjust the issue.

SOURCE: My 2001 Ford Escape runs rough before it warms up.

Well, fords are known for multiple O2 sensors... so I would have Autozone do a free diagnostic to see if

1. it really is an O2 sensor - and which one
2. eliminate the power feed to the injection/choke circuit.

2003 dodge 2500 diesel has a really rough idle and runs rough at low speeds, dies at times when at idle or when i let off the gas at around 20 mph . Has been getting worse at idle but runs down the hi way...


There could be all sorts of problems considering the age of the vehicle from electronic to engine valve seats and only a back to basics approach can fully evaluate the situation - lots of checking and lots of time...

A rough idle could mean a misfire confined to just one or two cylinders or it could be a couple of cylinders that are working but inefficient or it could all be intermittent.

If the car was mine I would begin by removing the injectors and having them checked and if any swarf is found inside it will place a question mark over the high pressure pump.

it sounds like you should check the wire harness for the injectors and the glow plugs they are molded into your valve cover gaskets and over time the little tab that holds them together breaks and you get a loose connection you will have to pull the valve covers to check

Bought 5.0 engine with systemax installed. Said it ran great. I installed the engine and just put the a 255LPH fuel pump in. Adjusted fuel regulator to 42 PSI. Runs REAL ruff. Won't idle by itself. Black...


I think your 88 mustang contols the fuel air mix with a manifold absolute pressure sensor. Ive seen were the vacume line going into one has worked loose or broken cousing rough idle and throttle. llso check that the idle air control valve isn't plugged up with soot. This would also result in rough or loping idle but would be fine once the engine is hot. Let me know if this was helpful, good luck.
