Everything works fine except the CEL is on intermittantly and the engine won't back off when I take my foot of the gas (intermittantly). It almost luck reluctant cruise control. It just kind of eases off eventually. I've put into neutral a couple of times and it just revs up unloaded and then eases off. I went to AutoZone and coded at 331 (?) The guy there said I should clean out my IAC and EGR valves? What? How? Thanks 1995 Merc.

The guy there said I should clean out my IAC and EGR valves? What? How? Thanks according to my haynes manual there is no code 331...there are codes in the range of 326-337 and those all have to do with problems with the egr valve and/or its related components... sounds to me like its time for u the do the egr port cleaning so many of us have had to do on our own cars lately...go to the mods sections ( i think) and look for a how-to on cleaning the egr ports behind the throttle body...not very hard as i was able to do it and im a mo-ron ... get yourself a haynes manual and study up on the how-to posted here and check out the pics they were a great help to me....u'll have to find a throttle body gasket to replace the old one and u'll need a can of throttle body or intake cleaner (i used b12 chemtool intake cleaner)...it worked great and i only needed a small can....also u'll need either a small pick and hook type tool set (found at walmart and/or lowes) or as i used a small screwdriver that came in my computer tool set ..its too small to use on the pc but was perfect for chiseling out the carbon deposits... the problem is that carbon builds up in the passages and on the back of the throttle body clogging up the egr passages and in turn making your car run weird it also involves removing the throttle body, acelerator/cruise cables so that would be a good time to give them a quick spray as well...some of us have noticed a sticking feeling in teh gas pedal dont be afraid its easy...i took my time and let my car sit for a few days while i did that and cleaned my filter and maf as well but it can be done in a couple hrs or so if working straight thru the other problem with the high revs is throttle hang and the posted link indicates...a pretty normal occurance on the mtx cars....the dirty egr is common too good luck and ask away if u need more help 99 expedition eddie bauer, 5.4 v8, k&n drop-in, 3" magnaflow catback and gas mileage that makes the contour look like a hybrid

The following is from the Ford TSP: Diagnostic Trouble Codes (DTCs) P0326 (KS1) and P0331 (KS2) indicate spark knock has not been sensed. DTC P0325 (KS1) and P0330 (KS2) with MIL on indicate spark knock has not been sensed. A spark knock occurred and the sensor circuitry did not respond by adjusting spark timing. Possible causes: -- PCM not receiving the signal at high altitude. -- Open or short in harness. -- Damaged knock sensor. -- Damaged PCM. * Key off. * Disconnect PCM. Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary. * Install breakout box, connect PCM. * Key on. * Read DC voltage between suspect Knock Sensor signal Test Pin and the SIG RTN Test Pin at the breakout box. * Is the reading between 2.4 and 2.6 volts? 96 Contour SE Duratec V6 24-valve 2.5L ATX 108,000 mi.

I would agree with gdub about there being no 331 code for the 95s. A dirty EGR/intake and carbon build up could explain a lot including the hanging throttle. Might want to clean the TB itself and check that the return spring and cables are in good working order. Scott 95 SE-2.5L ATX (Sold, but not forgotten...)

Everything seems cool in that dept now, but I don't want to wait until I'm stuck on the side of the road. 1995 Merc.

No way to tell without taking the impeller off and looking at it (white vs. the older black plaster impellers) It's pretty easy to remove -- there's a howto in the FAQ. -Lance Lance Kinley CEG Webmaster 95 SE, "Cassandra" 10 years!
