Chevrolet Repair: 89 cavalier fuel filter and idles rough, proper fuel, z24

Question
Hi, i just bought this 89 Z24 with 106km on it which is amazing but i just replaced a few parts. but the problem is the is idles pretty rough and you can really smell fumes coming from it... strongly. i was wondering what you think it would be??? what do i need to make it idle and run nice???

Answer
Hi Justin.... could be a number of things...what did you replace...if it was fuel filter...is it on the right way...make sure direction of flow is the right way...could you have broken return line...make sure you have proper fuel pressure..... hope this helps...merry christmas
