hesitation on start up
Iv'e noticed the last two mornings(cold out), that when i start my truck it hesitates, idles way low and then comes back up to normal and is then fine. Not a big deal, but I didn't think it was normal. I have a 97, 4.6. Recently has had plugs,wires,air filter, I just cleaned the MAF and sprayed sea foam into the throttle body to clean it and the intake. Also just changed my fuel filter/injector cleaner. If anybody has any ideas i would greatly appreciate any input. Also, is it possible to clean the 02 sensors? I know there are other sensors that get dirty and give false readings, and I was just wondering if that is ever done. THANKS!
