Evo III misfire on 1 & 2
Hello,
I need help figuring out out this issue with my car. i was driving home from work when i just suddenly lost a significant amount of power to my car. Come to find out my 1 & 2 engine banks are dead. I put brand new spark plugs, swapped around the spark plug wires on the distubutor and the engine itself and the problem stayed on 1 & 2. I know fact im getting spark on all four as ive seen it and heard it. so i checked the fuel injectors with a simple trick of putting a flat head to the metal part while the engine is on and listening if i can hear it pulsing. I heard it pulsing and didnt troubleshoot any further. So now im thinking maybe a clog in the fuel rail is blocking 1 & 2 maybe??? Any help would greatly appreciated i just wanna drive my car.

First off thank you for the reply. I have not done a compression test yet just because I don’t have a compression gauge and I’ll be able to check my fuel filter today when I get home. My question is could an engine just randomly lose compression without there being some sort of pop or bang or something?

Certainly. It could have a failed headgasket between the 1st and 2nd cylinders, or possibly an intake manifold gasket. Neither needs to come with a pop or a bang. Do a boost leak test if you haven't done so already, it may give you some valuable information.
