My 1999 tahoe is shaking when I put it in reverse or drive it gets worse when I push on the gas. I have have changed all the plugs and wires what else could it be?
Had it run on a machine at auto zone
and they said it was misfire or
oxygen sensor! Changed all plugs
and wires .
get a cheap (less than 20) automotive scanner...to find out yourself else take to an autoparts store will read them for free~
a bad ground...1/0 battery cable to chassis connection should be free of corrosion...with every start this one creates a "semi-conductor" condition...wirebrush this connection to allow "clean" power to the ECU~
when you've provides a full GROUNDed 12 volts to all components....reset the trouble codes using that device~
Well the idiot at the parts store cleared my codes after he run it a sec time after I changed all the wires and plugs
they'll come back if the computer says "warning will robinson" and flaps it's arms about~
99 tahoe. is it the 5.7 v8 or the 5.3?
5.7
a defective MAP or 02 will show on your "re-up" after reset~...that's what I was getting at with the B9 control robot reference~ with renewed ground (wirebrush the 1/0 to the chassis) these codes may NOT show...that's what I'm countin' on~
the 5.7 has the spider injector known to have the pressure regulator on it start leaking. Have a fuel pressure and leakdown test done on it. If you could give the actual code and not the description that would help me out
My truck is also a 99 Sport 2 door it is shaking an I replaced tires an had to replace stabilizer bar cuz it broke can someone tell me what is the problem. ..Thank you
Just curious, so was it the 02?
