hyundai sonata acceleration problem?
i have a 2000 hyundai sonata 2.5 v6, the transmission pops and gts stuck in 3rd gear, it used to do ok accelerating but now it hardly makes it up a hill, i am thinking it might be a sensor cause when i took it in to get it checked the computer put out all kinds of weird codes the people at the shop didnt even know what was going on. If anyone could give me any advice/help thanks in advance A: Could be the fuel pump does not pump up to specified fuel pressure to accellerate .
