Another thing I had to do.... Was kind of a PITA.... Well, was really not too bad but took a minute to diagnose correctly. The guy I bought it from complained of a slight miss every now and again at low RPM, at first I didn't really notice it, but then.... I did.... And it started getting worse, missing at more RPM range and eventually completely dropping the #1 cyliner....
Great.....
I did the normal tuneup stuff.... No fix....
Timing... Nope....
Adjust the valves... Nope.... They were fine.... (fixed leaky valve cover seal though)
Looked for vacuum leaks... Nope....
Grounds... Nope....
Did a buncha research, learned about some bad OEM splicing on the injector signal wires that commonly become a problem. So, I tore into the harness, found them. They looked OK, not great, but not horrible either. Regardless, I cut out and soldered in new connections/splices and put everything back together. Fingers crossed!
Nope....
Now I'm frustrated....
So, I pull the injectors.... YEP.... Couple of the pigtail plugs were cracked/broken, and the injectors themselves looked like poop. Soldered in some new pigtails, put 4 rebuilt injectors in and it runs perfect again. The kid told me the engine had ~90,000 on it when he swapped it in. I'm thinking more like 190,000. This is how they looked....



Sooooo, since then it's been trouble AND leak free.... It was a lil bit frustrating, but I'm still happy with my purchase and now the toy and are getting along great. Every relationship has its ups and downs right!? :-p
