I just delt with this on my’99 great prix. It’s pretty easy to clean (6. 99 for MAF Sensor cleaner) based on where the place of it’s. It’s typically found in between the Air Cleaner and Throttle Body. Just spray it 10 – 13 times being cautious not to really touch the small wires. I saved myself $160 by cleaning it instead of purchasing a new one. $600 to clean and replace?? typically you do one for the other, clean it or replace it. $600 sounds like lots although. It seems like the sensor is found in the airfilter box. It’ll be a small protusion with 2 little wires.
Etails as to which intake and exhaust valve is set. What you want to do is set each individual lifter when the camshaft isn’t engaging the lifter to be set. I can only assume you’re refering to hydrdaulic lifters, as which these information pertain. Start at Top Dead Center( #1 cylinder will be all the way up with intake and exhaust lifters down). With new parts, apply assembly lube to the cam lobes, the complete lifter (cautious not to input the little hole where the lifter rod sets), lifter rod ends, and the regions where the rocker arm makes contact with the lifter rod and the valve stem. It’s easy to clean out a new cam before oil gets to it throughout initial start up. If you’re simply readjusting a working cam/lifter combo be sure everything is oiled well. Push the lifter down til it rests on the camshaft. If the lifter is down (about flush with block) it’s prepared to be set. If the lifter is up at all, wait for the next revolution. Set the lifter by gradually tightening the rocker nut and wiggling/spinning the lifter rod till the lifter rod doesn’t freely move/turn. Turn the rocker nut another 3/4 of a turn. This will set the plunger in mid travel. Repeat for all other lifters not lifting. Now turn the crankshaft one complete revolution, and set the other lifters. Can set eight lifters each crank position. (answers.com)
We bench sync both mechanical slide carbs (like VM series) and constant velocity carbs (like CV, CVK, BS, etc) The bench sync on mechanical slide carbs is pretty correct. The constant velocity carbs isn’t so much so. The reason is that we do not sync the slides but the throttle butterflies. Once we have them all closed, we open the throttle butterflies with the idle screw, then attempt to get each throttle butterfly cracked the same amount but this is done by eye and to idle properly, this crack between venturi and butterfly is small. For this reason, we suggest contstant velocity type carburetors be synchronized using vacuum gauges. The bike will start and run but will be smoother after synchronizing with gauges. (wgcarbs.com)
Hello, I just replaced all the Low & High Beam bulbs on my 2008 Trailblazer. All I did was remove the Air Filter box (5-minutes) then removed the battery & brace (5-minutes) then popped off all the rubber seals covering the 4 bulbs, then replaced each bulb (10-minutes) replaced the rubber seals, replaced the Air Filter Box, replaced the battery & brace (total job time about 35 minutes). No have to remove grill or side marker lamps etc. Simple job, no problems. (cargurus.com)
