losing power while on the highway
My ford 1992 f250 strarted fine this morning, but while on the highway (going about 70mph) it started to jump a little and felt like it was losing power. I noticed a little bit of smoke blowing out of the tailpipe. It continued to get worse and worse and I thought it was going to stall but I made it to school.
I am really hoping someone can help.
I was wondering if it could be a clugged fliter of leak and praying it is not an injection pump problem or even worse internal engine problem.
Thanks in advance
