A couple months ago I put the car in the shop to get tune-up and the radiator replaced with a new one. Got the car out and right away I noticed it was losing coolant. One of the coolant hoses had come unattached (and/or was not correctly attached in the first place after the radiator swap-out). Took the car back and they fixed that problem, no charge.
Ok fast forward to now. Car starts running choppy, like on 7 cylinders. Took it in. They diagnosed pretty quick which cylinder and why: intake manifold gasket causing coolant to leak down around one of the plugs and causing a short with that plug.
My question to you all: Is it possible that when, a couple months ago they were doing the tune-up and radiator/hose work, they could have caused the current problem?
Finally, is $500 a good price for parts & labor to go in and replace this gasket? Apparently, it is a lot of work just to get to the gasket because the part itself is cheap.
Thanks for any advice you can give!
