Hi everyone, Im posting this for a buddy of mine. He has a 2000 Blazer that just started spuddering. Its not at any particular speed. The other weird thing that its doing is that he had it in park, stepped on the gas to about 2k RPM. The speedometer started showing that he was doing about 4-10mph, also the gas guage would jump from empty to full. He made sure there is gas in the truck also.

Has anyone else ever experianced this type of issue?

 

Did he drive through deep water or something?
Sounds like the computer module is going bad?

 

No, this is actually his wifes truck so it hasnt even left the pavement! LOL Its defiently something electrical. Its not throwing out any codes so I dont even have a place to start looking, Im just kinda stumped with this one.
