I bought this 1987 Honda Accord Lx from a gentelman who said it had carburator problems so the mechanics said. I want to take the car into the shop but before getting skrewed I wanna know exactly what I should expect to pay and for that I want to knowthe facts..does a honda accord lx have a regular carburator or a dual fuel Injector?

It could have either. All you need to do is open the hood and look at the air box. If it says PGM-FI then it's injected. Bring it to a Honda dealer if you are worried about getting screwed.
