I have a 1994 Chevy S10 Blazer with a V6 vortec engine. The problems I have are very little acceleration, a %26quot;service engine%26quot; light that comes on when I reach and exceede 50 MPH and stays on until I decellerate below 45 MPH. Also I'm having trouble reaching 55 MPH. When I try to push the gas peddal to accelerate, it will make the car slow down and eventully make it %26quot;die.%26quot; When It %26quot;dies%26quot;, all the lights on the dash come on, the power steering goes, and the breaks are very hard to push, and it will just stall out. Sometimes it starts right back up, but other times it takes about 5 mins to restart the car.
I've taken it to 3 mechanics, and they told me to change the spark plugs (I did-didnt work), change the fuel filter (did, still didnt work) and to get an oil change and air filter change (did, and STILL didn't work).
