Hi, I’m Cary and I’ll be helping you today.
Please understand that I can't smell, hear, or touch the vehicle, so patience is appreciated. Before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating..

Do you feel an engine misfire? Or just a no power like your pulling a trailer behind you that's too heavy?

Not misfiring ! Just no power!
Expert:  Cary York replied 10 months ago.

I would suspect a clogged exhaust or fuel issue. Normally with a fuel issue (lack of fuel) you would get a misfire (lean condition). Do you hear a whistling or exhaust leak on acceleration?

I would drop the exhaust pipe from the manifold and see if that corrects the lack of power.

Remember if you rate me we can still continue to discussion.
