2010 Chevrolet Blazer Repair Question
S10 Blazer engine miss
Also, there are no check engine codes present.
I'm thinking with 130k miles on the engine the mis-fire could be coming from a intermittently leaking engine valve or two. I guess a compression test is the next thing I'm going to have to do. But, I'm not sure if a small or random leak would even show up. I could use some help with this mis-fire.
random misfires are weird there could be so many things causing it , this calls for back to basics testing unless there are codes , vacuum leaks , fuel pressure and fuel bleed off , if it misfires the ecm will hit the mil soon i cant believe its not on now , let us know we will try and get you fixed, oh have you had to add coolant since this problem ??? nd how did the plugs look
oh and leave some feedback if you were happy with your help , we all donate our time here helping others free of charge
