OK everyone, got the 93 running really well, pulls great (well as great as 114 hp can pull 3000 lbs!).
Issue is, first start of the day takes 2 tries to get it fired, then it idles like a bar tender shaking James Bonds martini for a minute or so, then settles down. Runs great otherwise, as I stated pulls real well, idles smooth (or as smooth as red blocks do) subsequent starts are fine, 1 hit of the starter and she goes into a nice idle.
What have I done:
- Checked/replaced some iffy vacuum lines.
- Checked wires/plugs for loose connections, not torqued down since head gasket job 6 months back. All is well.
- Had poor running overall a few weeks back, replaced map sensor (had start issue prior to this), cured low power issue.
- FAQ says for poor cold starts w/Regina replace FPR, mine seemed to registor low so since mine was 19 years old, 65 bucks and 20 minutes got me a new one installed. I have 36 psi at idle, disconnecting vac line, gives me ~40 psi, not the 43.5 psi that is called for. Fuel pump getting tired?.
- Radio suppression relay is new.
- Cleaned and set throttle (again), got it right this time, no hesistation from standing start. Made sure all vac ports were not clogged.
- Fuel filter has less than 10,000 miies on it.
- Lots of searching says this problem isn't uncommon on these older cars.
I'm thinking the idle air control valve (which I cleaned) might be sticky after a long sit overnight?
Anyone else got any thoughts, need 2 or 3 more years out of this wagon as my daughter drives it, it's only got ~175 kmiles on it, so it's just broken in.
Sorry to be so long, but figure I'd lay it out there.
Mike
