[#1 laser]

i got a 1990 plymouth laser 2.o turbo and it shoots a blue flame out the exhaust i think it might be either rich or lean but imnot to familiar with this but it uses a lot of gas and when i turn off the engine it smells like gasw really bad so but i need a o2 sensor and a knock sensor

A friend of mine drives a 89 rx7 turbo that shoots blue flames out the exhaust in between shifts due to the test pipe. Your cat may be worn out because it is not filtering the gas which instead is being burned blue.

RX-7s naturally shoot flames. To the OP you need to fix what you know is wrong then go from there to diagnose.
