I test drove a 08 caliber today. It has the misfire issuer and is getting the CEL for misfire also. Owner changed the spark plugs and 1 coil. I am pretty sure it's a bad injector since he hasn't touched those. BUT before I buy it. How much does it cost to have the TSB flash performed on the PCM. Shouldn't this be covered under warranty or recall? Vehicle has 72,000 miles. What are my options...help me decide if I should buy or not. Also maybe give me some thoughts on how you like these vehicles. Have had an 05 caravan for many years and love it.
