 Subject: What now?

Message:
I have a 98 Dakota V6 giving me nothing but problems. When you start the truck up when it's cold it runs perfect. However, as soon as the engine starts to reach normal operating temperature, it sounds like its knocking under acceleration. I checked the timing tonight and it seems ok. I have recently replaced the plugs, wires, cap and rotor and I don't know what else to do. Can someone please help me out with this?

Try a compression test and look at the spark plugs again. Check that you have an appropriate heat range, and the spark gap. Sounds like an ignition issue. Verify coil condition and if you have cheap autolite ignition wires, make some new performance wires or buy a nice set. What kind of mpg are you seeing? Any other problems like smoke or adding oil between oil changes?

Check out your oxygen sensor as well. Has it ever been replaced?

I had the same prob with my 97, it ended up being the IAC AND the 02 sensor. Anyway, try this- clean your throttle body with some carb cleaner and go ahead and clean your IAC valve on the back of the throttle body (disconnect it and clean it). This could fix it, but it made mine worse (then I knew the IAC was bad), so I bought a new IAC, after I installed the new IAC, THEN the check engine light came on and threw the code for the O2 sensor. New IAC+O2 sensor= good as new. Hope that helped ya. Any ?'s, feel free...

Probably the ECM hadn't yet learned the new AIC and it fouled up the mixture, which tripped the O2 sensor code. I'll bet that had you driven it awhile and ignored the O2 sensor code, then reset it several days later, you would have found nothing wrong with the sensor.
Bad O2 sensors don't typically cause knocking.

could be a bad belly pan gaskget resulting it air coming in from the lifter valley. many times that results in pinging. that would also explain why it does it once it warms up because the aluminum manifold expands faster then the steel plate resulting in a leak..when cold it seals. look down through the throttle body with a flash light and look for excessive oil (puddles). that is one way to identify it. another more dangerous way is to pull the pcv valve out, and the breather on the other valve cover seal one side with tape or something and put your hand over the pcv side at idle. you should feel some pressure build up if the gasket is good. if it is bad you will get a suction.
