Oxygen sensors and/or too small cat converters. I had exact problem. I have same truck.
Current gap is .065. Called for .060. What is "too much" or "too little" gap amount? I plan on replacing, but do I need to w/ this gap?
Simple Rear Brake Question 99 GMC Yukon 5.7L Vortec 8thVIN/"R" 4wd Need rear brakes. Do I replace just shoes? or do I replace entire drum? Should I replace Drum and shoes and get a "kit" as well for replacing all of the springs, etc...?
5.7L V8 Auto 4wd trans (4L60E)Changed trans fluid/filter/seal/gasket. All good. Noticed rear TRANSFER case "dripping" fluid. Removed plug and "milky/red/white" fluid drains...only about 1/2 quart. I replaced w/ Dex6 Trans fluid. I put back in 2 qts. Tiny leak, ok a year ago, now the thing is "dripping". I get up in there and with a white cloth and cleaner, and clean the whole thing to find a hairline crack, and I mean a hairline on the back side above but not in one of the bottom bolt housings. I put EPOXY on it for now. Other than replacement, any ideas on sealing? Can I spot weld or solder it? Any ideas appreciated.
What tips, tricks or really good ideas do you have on removing distributor and re-installing new on. I know to disconnect all wires. Remove cap and rotor. Remove bolt, replace exactly Exactly back where I pulled it from. I read Chilton's so I have the basics down but there are always un-forseen issues not in books.
I got myself into a real pickle here... 99 GMC Yukon xlt V8 Vortec 350 Gas 4wd re-attaching distributor cap after replacing sensor. Must be original DISTRIBUTOR. The screw holds where the cap meets the distributor broke off. WTF? Yes the distributor cap is actually being held on by Duct tape. This is not good at all. There has to be a solution to this. Anyone have an idea on how to re-attach the Distributor Cap to Distributor? Both seem to be in good working order otherwise. Reagan
5.7 L 350 Vortec V8 Gas 99 GMC Yukon. 4WD. Verified transmission: 4L60E w/ deep pan. In '07 i had trans mission re-built (maybe not important) and so...I am replacing a solenoid inside the transmission pan/driver's side. So i must remove pan. NO DRAIN PLUG. NO PLUG Anywhere on the pan. I see the divot where the drain plug should be however no plug has been drilled, it is a smooth divot. Could this be? Could this be a new pan the mechanic put on? What gives? Any clues on where a plug would be? How do I drain then? Di I drill hole and plug later? Can I just loosen pan? Will 8 qts of Tran fluid dump everywhere? I loosened the plug on the rear transfer case and about a cup of milky red substance poured out and that was all. This can not be trans fluid..? Not near enough, however must I replace this fluid? With the blue or red transfer case fluid? Please help soon...drain plug issue most important.
P1345 says Crank and Cam position sensor correlation. What does this mean? other than they are not in correlation. I have been to mechanic, he hooks up "machine" to correlate them, yet check engine light/code stays on even when his computer says they are in synch. Do I need to replace Crank and/or Cam position sensors?
Intake Manifold Vacuum hose that is not on the ported throttle body. I connect the vacuum gauge to this hose for testing...Can I use thhe PCV hose? THe EVAP hose and or the Brake Power booster line? Instructions are vague as to where exactly to connect Vacuum Tester Dial I have. R
Where is the physical location of the sensor/Solenoid for 2-3 shift? Transmission? How do you tell which one you have? Do I have 4L60E or 4L80E?
5.7l Vortec. 200k miles. New fuel injectors. Will changing CMP sensor solve this problem?...perhaps? Getting terrible mileage for 4wd XLT Yukon. Any suggestions on getting better out of this engine?
