alright so i went to a friends shop today and he ran a test and said the misfires were in 1,3,5, and 7 cylinders. what could be causing that?

 

[SunlitComet]

That is the the entire left cylinder bank. Unless only those injectors or spark system for that side is malfunctioning, I would look into a damaged converter or head damage. Hit up an exhaust shop for a back pressure test. It should be cheap and check the left bank plugs and post pics here for diagnosis.

i did have an issue with a coolant hose quick disconnect on that side and when it blew out is when all this started, what could that have done possibly?

 

[SunlitComet]

the quick disconnect is on the right side of manifold not left. Only thing I can think of with that is perhaps the residual coolant is deteriorating spark wires or something.

 

[spivey94]

O ok I didn't know if it was left side looking under the Hood or from the drivers seat. Now I sound really dumb! Well I guess ill start replacing plugs and wires then huh?

 

[SunlitComet]

inspect them first.

 

[BattelWagun]

I don't think its the ignition, I'm thinking heads or cats

 

[gpracer1]

I would check the driver side O2 sensor and wiring also.
Does it do it when cold, or only when the engine is warmed up?

 

[spivey94]

gpracer1, it pretty much does it all the time and now it has started to smoke after i changed my plugs, wires, rotor, and cap. i was told to check the EGR valve so i pulled it off but i really dont know exactly what im looking for.
