Questions & Answers

Mechanic Q: What the....?

Well, waiting for almost a week for an answer is a waste of my time and effort trying to explain my car issues. It seems like no one ever gets a final answer or anything fixed by what I've read. Thanks anyway.

Mechanic Q: Rough idle?

Once the truck reaches operating temp, it idles a little rough. I've tried everything that I can think of to smooth it out. Tune up and also sprayed throttle body (CRC) cleaner in it and cleaned the IAC (oiled the seal). Also used fuel injection cleaners in the gas tank. Listened for vacuum leaks and sprayed the vacuum lines with the cleaner while it was running while waiting for the idle to change, thinking that would find a leak. Other then that, it runs great, just very annoying to me. Can you help me with this? Thanks

Mechanic Q: Key pad on drivers door?

The key pad works when you lock the truck by pushing the "9" and "0" at the same time but I can not unlock it. There is no previous code anywhere on the truck or owners manual. Can it be reset to place your own code? Is there a trick to it? I followed what the manual said and couldn't get it to work. Please give me a hand with this. Thanks.

A: Idle not perfect?

Thanks for the response.... The PO300 code that they gave me on their little printout said. 1. Ignition system fault 2. fuel system fault 3. Large vacuum leak 4. MAF sensor fault 5. AF/HO2s (air-fuel/heated O2 sensor) sensor fault Reading all the threads here, one struck my was to clean the IAC, TPS and MAF sensor, but don't know how the clean them yet. I have a Chiltons manual coming in the mail. Should be in tommorrow. The Xterra was only driven 5,000 miles in the last 5 years due to the owner passing away. The wife didn't drive it too much. The tune up I gave it included, Spark plugs and wires, fuel filter, PCV, Distibutor cap and rotor. Have not checked the timing. Looked for and listened for a vacuum leak, but nothing. The first tune up since it was bought new. Good color on the spark plugs, but the plugs were pretty much burned away, like you could tell they where the originals. It does run lean and it dosen't matter if it's hot or cold when this all happens. I don't know what else to say about it. The hanging harness.....looked for a place for it to go for quite a while. No idea. What next? and thanks for your help.
