I have a 1996 Z71 Pick up truck 4wd. At any moment (usually traveling 50-60 mph) the speedometer will begin dropping to zero.  The dash lights will light up leaving the ABS light to stay on.  You have steering control but when you press down on the gas, the engine raves up.  Then all of a sudden, it will ‘kick’ in and you continue driving like normal.  Sometimes it will immediately correct itself while other times, you best pull over and wait for it to ‘kick in’.  Yesterday, when it did it the speedometer would not work until it ‘kicked’ in.  It may to it today but not at all tomorrow.

How do I change a heater door actuator in my blazer and are there are any special tools I need and about how long does it take to do so I know if I need to take a day off to do so ….

Yesterday the Service Engine Soon light came on in my 2004 Chevy Blazer. I took it to Goodyear this morning for a diagnostic test and asked them also to change the oil since it has been a long time (since Sept. 09) since I did that. (I know my bad). The tech changed the oil, etc. and told me that the temp sensor was causing the error and I needed a new coolant temp sensor, thermostat & gasket, radiator hoses all replaced, coolant flush, radiator cap and decarb for almost $500. I had to be to work so I made an appointment for tomorrow morning. But as I drove away the light went out. Could it be all I needed was an oil change?  Help please!

just looking for the location of fuel pump. 1/2 ton chevy truck 93 v-6 auto trans

my 92 s-10 blazer 4.3l throttle body has the check engine light on and the oil pressure guage is reading low (at the lowest point on the guage). the oil level is at the full mark on the dipstick. as i am driving and accelerating the pressure rises slightly and the light flickers on and off.(check engine light) there is no difference in the performance of the motor and the gas mileage seems to be the same. could this reading on the guage be a problem with the pump, oil sending unit, oil pressure switch and how can I properly diagnose the problem myself? and should the vehicle still be driven before diagnosis? thank you in advance for your response.

So i posted about a week ago.. but it happened again. It simply does not pay to replace the ignition module anymore.. it keeps on frying. What other possibilities could it be?

The ignition coils on the 2nd and 4th cylinder of a 2.2L 4I Ecotec engine are burning out, even with repeatedly replacing the ignition module. It has trouble starting up, and then when it does, the engine runs rough, very rough actually. It’ll only run a little over 25mph, and takes a little more than 5 seconds to shit out of 2nd gear (this is an automatic). What is wrong?
