Hello Scotty, PLEASE I need help.. I have a 2002 nissan frontier 2.4 (KA24DE) manual transmission with an idling problem
After warms up the idle is rough, I did change all vacuum hoses, spark plugs, wires, distributor cap & rotor, IACV (idling air control valve), all injectors are working, used injector cleaner last time I fill up my gas tank, the 2 O2 sensors are good and all this time I haven't get a code.
I been in 2 mechanic shops and they told me just non sense stupid diagnostics. one said that the engine have a TBI (throttle body injector) and that I need to replaced the whole throttle body, the other one didn't have a clue what they were doing; so disappointed of all this mechanic shops and I feel really frustrated that I cannot find a trustworthy mechanic.
Any help will be appreciated
Thanks.
Please read the posting instructions. We didn't put them there for fun. Thanks.
Well there are so many reasons and engine can idle weird, but if it doesn't mainly run warm that normally is a problem with fuel injectors. As they age they wear and often will dribble and the dribbles make it run to rich and it'll idle crappy. When cold. An engine likes extra fuel so it doesn't affect it. They would be my gas. Of course. I'd have to put a scan tool on it and watch the dead on fuel injection system to get a better idea but doesn't injectors do wear out over time
Thank you very much, I really appreciate you take your time to answer my question..
I honestly would like you to take a look at it but, I live in Atlanta. Ga. so unfortunately is no way for you to look at it.
I have a scan tool but It doest tell me all the information that is needed, if you have any tips or suggestions of how to check the injectors please let me know.. or do you think that I should try to buy new injectors ?..
thanks again an I will look forward for you answer.
