Hey guys here's my problem. Tranny went out on my bronco (4.9L I6), it sat for 3 weeks. When I got it moving again, it the engine started acting funny. On occasion when I start it the idle drops dramatically almost killing it (I can watch the volt guage move from 10-14 volts) but it will clear up once I give it a rev. And at a cruising speed of about 40 it will jerk off and on, pretty sure it has to do with the rpm range but I don't know what is making it run so rough. Also when it is cold it will often die if I try to turn the wheel as I back out of somewhere or something. I was going to replace my oxygen sensor, if it isn't solved by that I was going to do the fuel filter, and then have to injectors cleaned. What is giving me so much trouble?!?!
Thanks,
Sam

 

what year? Is it EFI? I guess if it has an O2 sensor, it is efi. first thing to do is get the codes out of it. Could be many things and I can tell you from experience, a $40 code reader is cheaper than starting to replace things not knowing whats going on. Alot of auto parts stores will pull the codes for free, but that is where you should start.
