My 94 Olds 88 / 3800 (127k miles) has started to stall and surge when starting on cold mornings and check engine light comes on. Low coolant light also has been coming on occasionally over the last few months, but not at morning startup. Took it to a repair shop, told them my story and they checked it out. Said crank position and low coolant codes came up and that coolant is leaking into intake and on some sensor below throttle body causing the codes. They say it needs a new throttle body / intake kit to the tune of $250 plus $250 labor. All fluids levels are ok and clean, none have dropped noticeably. It idles fine and has plenty of power when warm. Haven't pulled the plugs but I just don't agree with this diagnosis and mechanic will not guarantee this $500 fix will cure problem. I thought it was an O2 sensor, but they say no. Any ideas?
