98 yukon runs rough

[phatal1320]

i just bought this yukon off my friend for 1500, has 183,000 miles on it and runs rough, he replaced Has a new camshaft sensor, O2 sensor, and said someone told him its probably a bad injector, any thoughts? and does this model have the "spider injectors"?

Yes it has the "spider" injection assembly. Does he not have any codes specifying a problem.

no codes, i got a buddy with the MT2500 snap on tool, and were going to drive it and see how all the injectors are doing hopefully i can resolve this issue.
