What causes an engine to run lean

Any neon that’s had the headgasket done in the last 8 years or so has more than likely gotten one of the revised multilayer ones that solve the problem. Unless it was put in by a hack.

cool. I didn’t know that there was a revised multilayer one. We got rid of the car 4 years ago. Is this the same neonmike from racepa?

logic, sorry I don’t have any info for your lean condition. Back on topic.
