After hours of reading about bucking, and sluggishness I'm chainging the chain on my 2.5. I'm hearing a little sound up front. The wrench to the crankshaft produced no sound. I have already changed Throttle Position Sensor. If I run into trouble with a bolt not coming out do I heat the bolt, or the area around it. Pictures coming soon. Lets hope I find the tensioner bad. I have read some nice stories about a brand new feel after a new chain. 148K on it.
