Code P0042 on 2004 envoy


Hi,
This Code can be related to a loose or bad fuel/gas cap. I'd confirm it's tight (a couple 'clicks') and not leaking - ensure you note air escaping when the cap is removed, which is normal.

Is the rear end on a 1988 Chevy Scottsdale the same one as used on a 1982 GMC Sierra? Our 82 is leaking and we are not flush atm, but the 88 is down for the count so can be ravaged for parts


Not at all the same the 82 rear diff is either a true 10 bolt gm, or a 12 bolt gm diff these were a lot stronger and standard size diffs made from stronger strength castings and materials also the spring perches were further inboard than the later models due to the frame being much narrower than the 88 the 88 rear diff can be installed but the mounts will need to be moved also the 88 diff is a metric design so lugs, brake lines ,brakes will all be different threads and will give a hassle converting the standard size lines on the 82 over to metric for it to work

Ok I am wondering if my motor in my 91 gmc 5.7 l b8 is a vortec or a 350 it has throttle body carb and not sure thought if I could interchange it with an older 350 ..


Here, is what I think you are asking. The TBI intake from a 91 will fit the same size engine from 88 to 95. The Vortec didn't come out till 96 I believe. So if your 91 is the original engine then it is not a Vortec motor. If you want to swap your 5.7 with another 5.7 (5.7 = 350) Then the 88-95 should work, Just double check your sensors and locations as the plugs may be different and or in different locations. I know my 88 GMC and my 94 chevy (both K1500's) were a little different. Hope this helps.

I was driveing my 88 gmc jimmy the other day and i


Try replacing the fusible links down by the starter. There are 2 and they look like a round rubber plug. Cut them out and splice the wires together. If they aren't there check the wire splices for corrosion. Use shrink tubeto cover the splices. Hope this helps.
