SOURCE: 1986 corvette running rich at idle, give it gas

have you tried checking the map sensor this can sometimes cause the engine to run oddly. also check for good spark check wires when its pitch black out check for wire arching. also check fuel pressure with a pressure guage.make sure cap and rotor are clean of deposits. keep searching and you will find the weak link.

SOURCE: I have a 96 cavalier z24. when I start it up the

See if there is a code in the computer and work from there. Find someone with an OBD2 code reader. If I'm not mistaken an OBD2 code reader works on 1996 and newer models. Could be a bad coil and you don't notice it when you first start it until it idles down, to check for that, while the engine is running, pull each wire off the spark plug, Each time you do that you should hear the engine struggle. Then pick back up once you plug it back to the spark plug. If you pull one and nothing happens to the engine, that could be all or part of the problem. Hope this helps.

A couple of things; you can't have any leaks in the exhaust system, in front of the cat, and you must have the correct mixture going into the engine. The cat must have at least .45% CO going into it in order to reduce NOx. Make sure you have the correct fuel pressure, good fuel filter, and the engine is not running too hot when you take the test. In fact you may want to try a cooler thermostat. The oxygen sensor is only a fuel trim device, the bulk of the systems fuel control is dictated by the MAF and MAP sensor if it has one. Bottom line; your engine is running too lean or there is air getting into the exhaust system before the cat. You may want to try another MAF sensor if you know the other factors are good. If you have access to a gas analyzer, drill a pre-cat hole and check pre-cat CO under load, at least .45% is critical.

I have a 2001 GMC Jimmy 4.3, it surges at low speed but when accelerated runs fine. Any idea what the cause might be?

If EGR comes up, take it off and clean it, see if that clears it up, it may be sticking. Would also clean your throttle body, and replace fuel filter.

OBD-11 codes 0403 & 0405

code p0403 refers to EGR --circuit malfunction===causes ---wiring--EGR solenoid---ECM
code p0405 refers to EGR valve position sensor A --low input===causes ---wiring ---short to ground---EGRF valve position sensor--- ECM.
By only changing the EGR valve you have not fixed the problems that cause the valve not to work.

Check for a vacuum leak around the EGR Valve . It is possible the EGR valve stuck open after cleaning it and causing an internal leak now.

I would highly suspect the "EGR backpressure sensor"
From experience and many conversations, a clooged EGR valve is almost unheard of these day. Get to an auto part store, were they can tell you what problem code(s) your car is getting, and possible good advice.

Gmc yukon 2001 dtc code po404

P0404 is Exhaust Gas Recirculation range/performance. This is usually due to the EGR valve moving slower then it should (sticking). You can try to clean it (the rod will need to move freely and don't spin the rod, it will damage the valve, just move it up and down) but if it doesn't work out then look for price and availability for a new one.

Would ignition coil problem cause 2001 Intrigue to misfire?

Not hard at all. Seven bolts and one connector. No computer work. But you need to know if it is the front coil or back coil. Front coil for cylinders 2, 4, 6. Rear for 1, 3, 5.

Replace the egr valve and solenoid if it is the mitsubishi motor, if it is the Dodge motor, then it comes as an assembly.

Replace egr valve

If the replaced the erg valve and the light came back on, you still have a problem, probably different then what they fixed.

Code 402 0n 2001 mazda tribute

A code P0402 most likely means one or more things has happened. The DPFE (differential pressure) sensor is faulty and needs to be replaced, there is a blockage in the EGR (most likely carbon buildup) or the EGR valve may not be opening due to a lack of vaccuum.

Egr vavle

The EGR valve is located right behind the multi port. ( the black plastic on top of the engine. it is kinda difficult to remove it if you have no experience with) I don't think is serviceable but some folks I know had told me that once removed, you can clean it with carburetor cleaner. the valve runs about 215 Dlls. at your local autoparts store.
