I changed a timing belt on a friends 2002 Tacoma 3.4 with 230,000 miles. Round 1: the truck had a real hard time starting and when it did start it ran poorly.
Round 2: I tore Iit back down thinking I must have installed the belt a tooth off. Miraculously the marks on the belt lined up again and all looked good. I pulled the belt and made sure it was the same as the old one. All was good. My best guess was the cam sensor may be going bad so I replaced it. Now it starts right up but still very sluggish.
Round 3: Replaced the spark plugs and no change.
Any suggestions as where to go next? I saw a video suggesting the crank cog could be worn and miss aligned. Any suggestions will be welcomed. BYW no check engine light.
