Problem:
The engine on my '89 Buick Century(V6) has lost much of its power. It doesn't accelerate well, it climbs hills at no more than 25 mph, and the engine revs very high when going on the freeway. I first thought it was a transmission problem because it seems like it is not shifting when it needs to, but I took it to a tran specialist and he said it just needed a tuneup.
So i've done this with my mechanic neighbor:
changed oil and filter
replaced sparkplugs and wires
replaced fuel filter
replaced air filter
flushed radiator
new battery
I still have the same problem, though my engine does run a little better. It also didn't pass DEQ after the tuneup, with HC just barely over the standard, and CO at 1.5 instead of 1.
Could it be a fuel injector problem, or perhaps the oxygen sensor or something electronic? How much would they cost? Thank you for any suggestions, I need to have my car fixed to drive it to Minnesota next week!
The check engine light turns on when I turn the key, but turns off after I start the car. The belt is fairly new, and my neighbor said it looks fine. Thanks for suggestions!
