1997 Camry - Heats too fast, and slight misfires. Sign In

I have a '97 Toyota Camry, 2.2 4 -cylinder at 150k miles. I was having a problem with overheating. The car would overheat within minutes (2 minutes tops) of turning it on, and driving.

My mechanic replaced the thermostat, radiator, some hoses, and coolant switch. (And perhaps some other things. These weren't all done at the same time.)

The above didn't work, and I brought it back. I suggested that there may be a clog in the coolant system (as I had mixed coolants a few months prior.) He told me he thought the same.

Anyway, he did something, I have the car, and now it doesn't overheat. However, it still heats up, now within a minute, to 'normal.' (Actually runs a bit cool, but it always did.)

Additionally, when I first started the car after I picked it up, the engine revved high, (around 2-3 rpm) and misfired a couple of times. Since then, the engine revs high on idle (about 1.5 rpm, whereas before it was a bit under 1) and I feel subtle misfires on a fairly often basis.

Additionally, when idling, I sometimes notice a small bit of white smoke coming from the exhaust (not sure if it was ever there before, but I'm getting paranoid at this point).

So... did my mechanic mess up a different system when fixing the coolant issue? Are these two issues somehow connected? It doesn't seem normal to heat up so fast, is there a problem I should be aware of? Is this all simply 'old age' and it's time to get a new car?

Thank you in advance.

You could have triggered a blow head gasket with the original overheating. Start out with getting it scanned for codes.

Planning on doing that - actually have an inspection due this month, and CE light is on.
