    93 motor swap issue

    I just released when I changed the egr stuff and put new pigtails on the purge solenoid is a newer version oval plug. Was that wired the other way or will it even work? I did it one wire at a time with the cutting and soldering but I could have very well got that one wrong.

    93 motor swap issue

    Well I pulled the old fugue regulator off and no gas came out of the return hose. So hopefully I'm thinking that's my rich culprit and why the vacuum line popped off was actually a good thing according to the smog guy. 1 Could this been a culprit of my EGR codes as well Because the computer was...

    93 motor swap issue

    I'm thinking new fuel pressure regulator. If the vacuum line being off helped. That make sense?

    93 motor swap issue

    Well it passed everything but high nox. And the smog shop said do to the low levels of the other gasses the cat was probably working fine. I found my fuel pump regulator vacuum line was off but the smog guy said that probably helped. Does that make any sense?

    93 motor swap issue

    Well finally got around to trying to smog it (over 650 hours of ot last year I didn't have time) it is running nicely. But failed with really high NO. And gross evap leak. Evap has been fixed. didn't realize I broke the line from tank to frame when installing new fuel pump. Would that also...
