need help with engine prob
 

hey all, i am a former 3rd gen owner and looking to buy another. a car i am looking at has an engine prob that i can't diagnose, so was wondering if any of you might have expirienced. Haven't done a compression test yet, but will do it as soon as i buy it... anyhoo the car will not start. it turns but will not start. i guess the recent owner removed the cat, and did a an exhaust job, and thats when the the probs started. he started expiriencing boost creep, and describes right b4 the car quit, he was driving down the road and felt like he hit a wall the power loss was so great. now it smells really gassy, and is blowing blue flames out the back like its getting surges in fuel... thanks in advance for your help :) andrew
