Heating exhaust pipes is either too lean or incorrect timing allowing unburnt fuel to burn in the exhaust pipes . Check valve clearance for the exhaust valves.

SOURCE: 2003 escape idling to high, exhaust pipes turning orange red, not cataylic

Your escape is a 3.0L duratec motor. Is the motor itself overheating or just the pipes? The high idle is often related to a dirty Idle Air Control module or IAC, which is located on the top of the motor near the throttle body. If you clean this, or replace it, after a few days the high idle is often times solved.

WHY IS MY CAR STILL OVERHEATING WHEN I HAVE REPLACED THE FAN CLUTCH,THERMOST


A clogged catalytic converter will restrict the flow of exhaust and cause heat to back up in the engine. Other causes include a crushed exhaust pipe or a collapsed double wall pipe. Check intake vacuum at idle. If intake vacuum reads low and continues to drop, inspect the exhaust system.

Codes wrettinpo401


A P0401 code is "generic"& only gives a "general" area in which to look. Exact OBDII/CAN nomenclature is: Exhaust gas recurculation, insufficient flow detetected. THAT IS PRETTY "GENERAL". It could be a sticking EGR valve. You muffler canister could have collapsed internally. Some better exhaust pipes (like Fords) are dual lined.a pipe within a pipe, & one of those collapsed. The catalytic converter can be getting plugged (they quit anywhere between 90,000. to 140,000. miles. THEN, may be something as simple as a vacuum hose, disconnected between the vacuum switching valve & the EGR.

    2003 escape idling to high, exhaust pipes turning orange red, not cataylic


    Hi Whitewolf108,

    Is your vehicle a turbo diesel? or if it's petrol, again does it have a turbo?.... The turbo can often cause the effect that your explaining, regarding the orange glow from the exhaust manifold.... To give any more advice, I'll need more info from you....Example: do you live at a high altitude?.....The type of engine?....Any modifications bolted on?.... When did the idling become too high, was anything done to the carburation around that time?
