2002 Gmc Envoy

[2002 GMC Envoy]

Posted in the wrong forum earlier...Hi...I own a 2002 GMC Envoy SLT with approximately, that I had purchased brand new...lately, while I am driving, I will suddenly lose power and the instrument cluster will flash all kinds of warnings...had the MAF sensor replaced, was ok for a couple of weeks and then it left me high and dry on the highway...it is not throwing any codes, so it's hard to narrow down the problem...all the grounds have been checked...the new thing now, is it is not shifting...anyone have any ideas as to why this is happening and what the possible fixes could be? Any help would be greatly appreciated. Thanks.

have it diag'd by a tech and you MAY find the ign switch is intermittant

 

do NOT throw parts at ,it'll pay for diagnoses

 

good luck
