Dear guys, GMC Yukon users ! Hello everybody !
Help, help, help !!! Neeeeeeeeeeds advice A.S.A.P. Just purchesed 1995 Yukon. Did not pay much for the car, but this is not a problem. The problem is that after the tune up and oil change the car's engine is kind of shaking on idle speed (N or P or D). Please note that this problem do not feels while driving on the fast speed (highway). Thought this is injectors ??? Sprayed the bottle of cleaner inside 2 two of them, than ran on chevron-techron (twice) to clean up the engine. Checked the air intake also -- clean, no problems there. Checked sparks on each wire -- good. Tune up done with dealer's AC Delco. Fuel used 93 - Amoco. No bull. No water in the fuel also. Used the water remover. So what is the freaking problem with this peace of GMC technology ??? Why I can not figure out what is the problem with that?? Dealer will charge me $ 85.00 dollars just to check the engine with no guarantee @ all if the finding the problem??? I am very handy and can do myself a lot of things -- just needs to know what to do????? Please somebody help me, GUYS !!!!!!!!
Regards, sincerely Greg and his shaking 5.7 vortec engine.
