    99 Tahoe - Trouble Accelerating / Hesitation

    Very interesting indeed. I had the same issue with the Cats first, and then a concurrent Fuel Pump Failure. Replaced everything including the O2 sensors. Did a full tune up but am still having the same RPM (hunting or searching) at low RPM's. I received a lot of feedback from forum...

    Radiator - Top Oil Cooler Leaking

    My two cents. All of the radiators are made in China unless you buy a high end brand. It's cheaper to make them there. The quality on mine from Advanced A was just fine. I also looked at one from A Zone which was a heave duty but did not fit the bottom rail so I had to get the thinner model...

    Radiator - Top Oil Cooler Leaking

    I have the same problem on a 99 Yukon. $100 will repair it. $230 will get you a new radiator. I bought a new one today and will be putting it in tomorrow. It's messy getting the old one out. If your lucky enough to get most of the fluid out of the drain, the rest of it will be a mess...

    Hard to open driver's door from inside

    I had this happen on a 4dr 99 Yuk. The first time the door hinge pins and bushings were worn and had to be replaced roughly $50 in parts. The second time, three years later, I had to replace the inside and ouside door handles. I did the outside one first (because it was physically broken...

    99 Yukon-Engine hunts on slight grades

    Thanks for all the advice! Just finished putting some AC Delco RapidFire platinum plugs in tonight. It looked to me like two of them were in worse shape than all the others. Will see how it does on the drive to work tomorrow.

    99 Yukon-Engine hunts on slight grades

    You raise an excellent point. I guess I just didn't think of it that way. I would have thought you would see a missing issue in other scenario's not just under a load condition. I put Autolite plugs in the last time. I will buy new ones (plugs, cap, rotor and wires) and put them in as...

    99 Yukon-Engine hunts on slight grades

    I did the inline fuel filter back in November. I did Plugs, cap, rotor, PCV and wire in November also. I did the Air filter on Sunday and an oil and filter in the beginning of June. Am I missing anything else in the tune up? When the gas tank was dropped it was clean and the old pump sock...

    99 Yukon-Engine hunts on slight grades

    :confused2:A little Background- Last week while coming back from the beach the engine lost power and RPM's dropped while driving up a hill at highway speed. This happened twice. Pulled over checked trans fluid and it was good. Called local $$$ Dealer and they suggest Catalytic converter. Was...
