May 12, 201015 yr Ok, first off--thanks to everyone who contributed advice on getting my old '91Loyale w/tbi back in working order. Now for the bad news/majorly irritating effing mystery: Nothing worked. First and foremost, I put the throttle stop screw back where the factory set it, replaced everything that was throwing a trouble code (egr solenoid, purge solenoid), checked MAF, bypass air valve, ox sensor, checked and cleaned the egr and replaced all the vacuum lines for good measure and put in new, properly gapped plugs and wires, pulled the distibutor cap for visual inspection of the contacts and rotor button (of course they were good), threw the meter on the CAS, checked the coil. Rechecked timing, all good there. Everything checks out. As far as the book is concerned the *%#@^& thing is in in perfect working order. And here's the really irritating part; I run it in the driveway and it doesn't miss or pop. I drive it around, everything is good and it runs smooth. I take it to the testing station and it's still running nice and smooth, no misses, no pops. As soon as the effing tech gets in the seat and closes the door to drive it into the bay it starts to pop. It FAILS in an epic fashion w/ the highest HC readings yet. I get it back home and of course the computer is throwing a code (1 long flash, 2 short flashes) telling me the starter switch (according to Haynes) is not working just right....soooooo....looks like I'm going to have to get back to work. Anyone know what/where the starter switch is? Am I correct in assuming that when the Haynes manual says 'starter' it really means 'ignition' switch? (This is a rhetorical question intended as a slam on Haynes. Unfortunately, subtle but cutting sarcasm doesn't translate very well into printed form.) If you have ideas on what's up, lay 'em on me. I've done everything short of having a long talk with the car while brandishing a 12-guage loaded with slugs.
