well this is a good one--just going over a spanking new motor my friend put in his tahoe-runs like ass-found dizzy to be a tooth off-had to use my scan tool to set the dizzy properly of course,then realized while looking at the scan tool the maf is doing nothing,and it throws a mass air code-clear it,comes back instantly,and trucks always had a stumble he said -even with old motor,never had a check engine light because the bulbs blown


what i need is the voltage reference's for each wire--i do have 5 volts at one wire already-i recall having continuity at the ground wire in the harness-cant recall what i saw at the 3rd wire,ill be going over the truck tuesday when the mass air meter comes in.

i just wanna be sure the ecm is doing its job basically-so far the 5 volts tells me it is-and meter is bad

see i knew yesterday even without a diagram something was wrong,that 12 volt signal is only supplying 2 volts--trucks on its way here now--i have some good ecm and engine harness diagrams now-and thanks for that signal reference too guys

got the new mass air in hand--gonna obviously have to swap an ecm or rewire the harness-we will see



wish me luck

hahaa i knew you were having some issues over there....



i didnt think you would show me points for a new truck anyway,lol





oh wanna hear a good story--?


the story of the v6 hyundia i did a timing belt on over the summer!!



the story of how at the time the engine mount that is bolted BEHIND the timing cover was ripped out of the block last time i went to work on it--looked like shitty metal fatigue-what was left of the threads was on the end of the bolts as i gently just removed em by fingertip-so i tapped and threaded the holes for a larger set of bolts-that held great--well once again the shitty aluminum pulled through taking the engine mount out of the block....but this time the bolt fell out-dropped down in between the timing belt and pulley and chewed the belt off till it snapped{how the customer did not notice his car was sounding fucked up boggles me}resulting in a blown motor?


he tried blaming me at first--but after reminding how he hasnt complained about the 2 other cars that run great that i fixed months ago{both higher quality cars like a nissan sentra and a mitsubishi outlander truck--yet his hyundia's that are over 100k miles old are shot!!


so i showed him the junkyards local listings on cars they put out to pasture -and he couldnt believe that theres suddenly 18 different kia's and hyundias there-all about the same mileage...all around the same years



you buy shit-you get shit--and no mechanic can fix a poor design flaw without wasting time...


oh and the recently repaired one from last week just destroyed a motor mount as well --but its the intermediate mount that bolts to the frame and engine mount--not the part bolted to the block{not yet anyway}


i have forbiden myelf from working on anymore 2.0 and 2.5 liter 4cyl and v6 motors-including the failure of a motor i have to swap now for someone-the landrover v6 2.5 disaster designed by dayco belts-that has slipped an engine sleeve...

that motor being swapped for a running one and trucks being sold-fast!!


i dont feel its coincidence that these motors are all failing at the same time-i call it the united states--buying foreign junk--and now us mechanics pay for it in stress..

well balancing out whats worth fixing-and being paid for-and whats truly wasting my time and aggravating me while doing so--and keeping my pockets lines and me happy is a tough one


guess it comes with territory--but i can of course refuse to service a car-wonderful thing about being my own boss--being able to tell the customer take a hike...
