Had my timing belt, water pump and thermostat replaced last week and noticed a subtle misfiring on cold start which stopped after driving a few blocks and warming up. I planned to get that checked after this weekend. Fast forward to today and the CEL came on along with the VSC Trac and VSC Off lights. My amateur diagnosis is that the t-belt was installed incorrectly and is off by a tooth or two resulting in a misfire. I've parked it and am having it towed in Monday but would welcome any thoughts on the root of the problem or any possible damage that might have occurred. Thank you.
