Well, I've been lurking and searching for over a week now taking in as much information as I can, and I'm still having problems, so I thought I'd suck it up and post my very own thread.
To start, I drive a 1987 Wagoneer with the Renix 4.0l. (AW4/NP242/D30F-D44R, don't think that's relevant but more info never hurt, eh?)
I started smelling gas in the cab, so I went to take a look and lo and behold, a few of the injectors were definitely leaking where the metal and plastic meet on the injector. I got a set of Ford 19# injectors, as I'd read on here that they're a pretty popular swap.
Problem is, now I have to give it almost full throttle to get it started, and it blows some white smoke for a little while until it warms up. It smells like it is running rich, but I don't see black smoke. When I'm driving above ~30mph and I give it just enough throttle to hold speed, it shakes alot. It idles alright, but shakes more than it used to, if i give some throttle it smooths out with higher RPM. If I give it alot of throttle and then let off quick it either dies, or almost does and then picks back up.
Fuel pressure at the rail checks out like it should, cap/rotor/plugs and wires are all new, along with 02 sensor and MAP. I reset the PCM by disconnecting the battery for a while, and then key on-headlights on-headlights off- key off. I read that it gathers data for 50 start up cycles.
Should I just drive it for a while and see if it evens itself out as the PCM gathers data? Can you guys think of anything obvious I may be missing? I'd like to apologize in advance if the answer is on this forum and I'm just an idiot, but I've been searching and the whole internets for a while and I'm not getting it.:dunno:
