I am not sure about the problems prior to me owning it.
At 117,000 miles, the catalytic converter went.
At 119,000 miles, the clutch fan went.
At 129,000 miles, the head had two cracks and it was warped.
Starter went at 130,000 miles.
Electrical fire at 130,000 miles.
Bad fuel injectors at 128,000 miles.
It is now at 141,000 miles and it smells like gas when it is running, causing the check engine light to come on and run somewhat poorly.
The truck is quick at first, but has no speed.
The body still looks perfect, but the internal components make it a piece of junk. My Sonoma isn't the only one that has had the major problems with the head. A friend of mine blew her head gasket on her '94 Sonoma and another friend with a '94 S-10 had the same problems I had.
My head gasket just went to, but everything else is OK. My truck is really quick off the start, but as no top end at all. The body is in perfect condition I have rims body kit and it is slammed to the ground. It is my project for the summer by the end of the summer it should hopefully look like a show truck I have my fingers crossed. O'yeah my catie is messed up to. O'Yeah it is a 94 Sonoma.
