Hey all,

I'm trying to put a 1999 9-5 wagon back on the road. It's an auto car with 151k on it. Long story short, it came into our shop with a leaking head gasket. Customer declined repair and abandoned the car. I bought it from the shop, and am trying to get it running.

Head was milled, new gasket installed, car starts and runs (fairly well), but will not idle. Does eventually set a CEL after multiple restarts with P0300 and P1300 codes. I know the car was run hot, so I ordered a replacement DI module and swapped it. No change in symptoms. Have a new crank sensor coming.

All intake connections and vacuum connections have been checked and rechecked.

If the crank sensor doesn't help, any other ideas?

Has the sump been opened up and checked for sludge? If the engine is running hot, there may be oil pressure issues which could be part of the problem.

Try swapping MAP and MAF sensors.

Try swapping MAP and MAF sensors.

Yes those sensors and O2

Crank sensor helped, would idle but not smoothly or in gear. Decided to check everything (aka pull valve cover to look at stuff), and found exhaust cam was one tooth advanced. Reset cam timing and all is good.

Side note: the cam gear setup on these engine sucks, or else I'm just spoiled by Jaguars.
