1997 t100

Hi guys, I'm lost i have a 1997 t100 I changed the timing belt 40,000 miles ago. The problem with the truck is when i get the truck into traffic it seems to bog down when i floor the petal. Is it possiable that I didn't put the timing belt on correctly or is there a chance the timing jumped a tooth? Or is it something else. I had the injectors cleaned no change. Please help.

I found the timing perfect. What I did find was a vacuum hose cracked from the brake booster to the manifold . replacedd hose and its fine. Runs like new.

One of the first things I did when I acquired my 1993 T-100 was to replace all the vacuum hoses. Glad you were able to figure it out and post the result. Thanks and welcome to the forums!
