90 LeSabre
 I usually hang in the Ford section, but have a question about a LeSabre. Uncle has a '90 LeSabre. He says it runs poorly, lurches? He also says the CEL comes on and it runs better. (Limp mode?) Yesterday it stalled & wouldn't restart, but after getting it towed home, it fired right up. I have an OBDII scanner, but nothing for the older stuff. I sent him to autozone, but they couldn't help him either. I know the info is sketchy at best. Can I jump out the plug on this car and watch the CEL to get the codes? I remember doing it on a car I had in the past. Thanks for the help. Rusty

Yes, you can jump a couple terminals on the OBD1 Connector to get the codes, as described in the preceeding link. A scanner is really a waste of money on the older OBD1 cars becuase all anybody really needs is a mangled paperclip. Codes really help to diagnose the problem, but from the description it sounds like a component is failing at operating temps...usually the crank sensor or coil packs. However, neither of those components usually give off a code (which would trip the check engine light). This leads me the to conclusion that there are possibly more than one problems. Basically, get the codes and we'll get your uncle squared away
