DRIVES OK IN FIRST THRU THIRD THEN BOGS OUT IN FOURTH AND FIFTH. :uhoh: I HAVE HAD THE TRUCK ALMOST TWO YEARS AND DROVE IT APPROX THIRTY FIVE MILES-AND THAT WAS LAST NIGHT WHEN I MOVED TO A NEW ADDRESS. I HATE BEING STRANDED IN THE MIDDLE OF NOWHERE. HELP!!!

It is a 1994 s-10 with a 2.2 ltr fuel injection w/ borg/warner manual trans. Ill get 8th vin number and mileage in about ten minutes.

Kinda cool. The lady who owned the s-10 before me moved to hawaii

OK, You'll need to take a look at your fuel pressure readings to ensure that they are in spec's. It shoould be reading 52 - 58 psi with the key on. Turn ket off and your pressure shouldn't drop more that 5 psi with in a 5 minute time frame. Post back what your findings.

Actually the book says 41 to 47 psi and shouldnt drop more than 5 psi with key on. And it is within specs.

Sorry should drop with engine on not more than 5 psi and it went to 38 psi.

And it has the mfi fuel injection system. Sorry, should have said that earlier

OK, When was the last time you had a full tune up? Are there any error codes? Have you checked to see if you have any arking plug wires?
