This truck run perfect the problem when I first start it in the morning, the first thing I smell in the cab is vinegar smell it doesn’t last very long at all.
I just wonder if my converter is going bad, it’s is original and it has 84,000 miles on the odometer.
One other thing after it’s warmed up and shut off I raised the hood to let it cool down before I put it in the garage and I smell a slight ordor of gasoline.
Could these 2 things be related ??????
Thanks in advances
Denny (aka roadyacht)

A couple of things you can check:

If you have an infrared thermometer, take a shot of the exhaust pipe at the CAT. There should be a pretty significant temp difference between inlet and outlet. The exhaust temp increases through the CAT and should be quite a bit hotter at the exhaust. The thermometers are available for under $30 from several vendors.

The fuel smell could be from a lazy injector. Pull the air cleaner and watch the spray pattern as you open the throttle and watch for anomalies. It should be a fine mist cone from idle to wide open. When you shut it off after driving, check for drips from the injectors.

It also wouldn’t hurt to do a pressure check.

Thank you so much Cowboy I will definitely check the converter I do have a heat gun so that won't be a problem here
I will also check the tbi for correct spray and look for a drip
Again many thanks
Denny
