I have an 89 camry with 175K miles. It starts fine and runs great until I get off the freeway going to work every day. As soon as I come to a stop it idles roughly and sometimes stalls. It also jerks when I take my foot off the accelerator. Tonight on my way home I noticed that it started losing power getting on the freeway. I changed the gas filter thinking that was it, but it didn't make much of a difference. I also changed the air filter and oil. I'm not much of a mechanic past tune ups so if anyone could share their thoughts I'd appreciate it.
