Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry your having this problem
is # ***** dead at idle or misfiring at idle or only when driving it ?
there were NO 300 codes before the work was done ?
is it setting this code at idle ? can you feel the miss ?
and your sure the firing order is correct ?
new cap ?
where these valve adjustable or just torque down style ?
ok right off the bad we had alot of issues with bad or defective caps right out of the box
can you first try another new cap ?
if it still misfires pull that bank of plugs and what are all 4 cylinders reading for compression ?
ok if the compression on that bank is all reading the same this issue is going to come down too a vacuum leak or rocker that fell off or push rod that has broken or fell out and if that checks out the only thing left is a cap OR an issue with the # ***** injector
you can always get me back for FREE through this post with any follow up with this question anytime as i do not get credit for my work until you rate us here
ok see if the compression is good and there are NO vacuum leaks
in area of the # ***** cylinder since /# ***** is the one misfiring
