My 1994 Mazda B3000, 3.0l Ford "Vulcan" v6, 54,000 miles (yes on a 1994!), is being a major PITA lately... Every morning when I go to start it up, it will start up, run ok for about 2 seconds, then all of a sudden run very rough, around 200 RPM, then stall and die. If I start it again, it always starts up and idles, but for the rest of the day it idles without stalling, but it idles rough and shakes quite a bit. When I drive it, it's virtually powerless, feels like I'm driving a Metro Geo again... It's also been guzzling gas, my 3.0 is turning a steady 13mpg
Here's what I know / have done...
-Brand New 02 plugs (didn't help)
-Cleaned MAF sensor connections (didn't help)
-Reset computer (didn't help)
-Seafoamed engine through gas tank, oil, and brake booster
-New plugs, new wires, cleaned distrubetor and cap...
I live in a very small Texas town and can't find anyone that can pull codes from a 1994... So that doesn't help me... Any suggestions?
