Hey fellas. Been a while since I've been on here, since I picked up a new truck... I've been trying to fix the Jimmy to sell lately and have a problem I can't figure out. It had an 0300 code for a while, along with EGR and TPS (which I've fixed)... It occasionally stalled, but mostly lost all power when accelerating from a dead stop. After replacing the two sensors, I drove it to the end of the block before it spazzed out again. The misfire is very noticeable, but no codes or CEL have come back up yet.

I have video, but no idea how to get it on here.

A little history...

Full tune up done last summer
Fuel pump/filter
Ignition coil (last week)
TPS (today)
EGR (last week)

Thanks,
Steve

 

What people usually do is upload the video to youtube and link it here.

 

Hopefully this works...

 

Anyone?
