Hey, just picked up an 86 lxi automatic with 48k miles. Body is in ok shape, was in minor accident on passenger side. Anyway, just wonder any good 50k maintenance things to do. I know serp belts were done within 10k miles. It has a an erratic idle in park that surges 1k to 1.5k rpm. Has warm heat and coolant topped off. Was told could be the cooling system. Vac lines are good. Thanks for any tips.
