Last week he drives his girlfriend home, and all is fine. Next morning he gets in to start it, and nothing. OK, no problem, go out and get a new starter and installed it. Bam! Fired up right away, with one hitch? It now is no longer the smooth running Bronco it has always been, but it is shaking the center console something fierce, and upon acceleration, get even worse.
HHmmmmhh. So I figured it couldn't have anything to do with the starter going out, right? So I decided to give it a complete tune up. Changed all spark plugs and wires, distributor cap and roter. Having never done this, I thought I was Mr. Goodwrench afterwards. As I get into the truck hoping any praying that it would actually fire up, IT DID! And man was it running good! In fact, I noticed immediately at highway speeds it was now running about 2,400 rpm instead of about 3,000 rpm's it use to run at the same speed. I figured, PROBLEM SOLVED! All day it ran GREAT!
That night he came home from his football game and said, dad, the truck is doing the same thing. In disbelief, I of course took my own test drive, and sure enough, the same problem as before. The same problem I had "fixed" earlier in the day.
Now, what do I do? I didn't change the coil because everyone told me they either work or they don't? Is that true? Like a light switch, either on or off? I just don't understand how after I changed the plugs, wires, rotor, and cap and it worked great, that the exact same problem came up within 12 hours of going away.
Any ideas would be helpful and appreciated.I am at a loss right now. Should I just shoot the darn thing or what?
OK, UPDATE! Now my son says the problem is intermittent? Sometimes it will run just like it should, other times it will shake violently upon acceleration, other times accelerates just fine. Good news is so far it has started every time, and gets him to where he needs to go. What could this possibly mean? What should I replace next?
have the same problem?
