Question about Chevrolet Chevy

2 Answers

I have a 1977 CruiseAir Motorhome with stock Chevy 454. Replaced the tranny 2 years ago with junkyard. Has run fine until last week when developed strange vibration that seems to be speed related (60 mph & up). Power doesn't seem to be affected, and isn't hard to handle. Just a "pulsing" vibration almost like crossing bridge grates (comes and goes with a frequency that increases with speed). Any ideas?

Possibly Ujoint going bad or driveline may need to be balanced-could also be a tire out of balance-another idea could be loose flex plate on engine or torque convetor bolts loose!!! :)

1995 Gmc Jimmy will not start.


Sounds more like the "crank position sensor" a small crack can cause your starting problems...NO, none of this means replace the motor:( YES do replace plugs, wires, clean air filter, spray out throttle body with injector cleaner, use specific "mass air flow sensor" spray cleaner only and clean that too...located near the air filter... A dose of the right TLC should add many miles of fun to your Blazer...Hope this helps.

96 chevy s10 ss runs rough misfires no engine codes


I am thinking it is your distributor. I had this happen just a few weeks ago. Check with local junkyards as I found a used(almost brand new) distrubutor for 100.00 opposed to almost 300.00 new. Same exact problem and also changed each thing you listed prior to finding out it was my distrubutor. My truck runs like it did before the issues started.

GM only has one V8 firing order as far as I know. That is 1-8-4-3-6-5-7-2. The distributor runs clockwise and #1 should be at 5 o'clock. Hope this helps.
