    That's an interesting problem. I have some questions;
    1. how often do you drive the vehicle in a month?
    2. when was the car's last tune-up?
    3. have you ever had this problem before?
    4. is the car fuel injection?
    5. have you changed the plugs recently? 
    6. is the coil/distributor original?


    thanks for the help with clarification. paul

Low compression on cylinder 1 bad skip if you idle it up the skip will go away and also it runs fine while driving


If there is low compression in one cylinder the fault wil be shown more at IDLING as the engine will not be smooth. So there will be reduced power and it might also skip.
In th long run you will have reduced power of the engine even as the engine will not show on higher RPM and thus the fuel useage will be more.
It will be good to check out and estimate to get the compression corrected to all cylinders.

Tip

How to Diagnose Your Engines Skip


Sometimes it's easy to tell if your engines got a skip. Other times its not so evident that a skip is what's causing your engine problems. Even when your know its a skip, deciding on which cylinder is the problem. This how to makes finding that problematic skip easy as pie.
Instructions
Things You'll Need:
infrared thermometer
Step 1
First thing you need to do is get yourself a infrared thermometer. Sounds fancy but they are not all that expensive, you can find them for under 50 dollars. These things are handy for so many things, trust me you will wonder how you ever got along without one.

Step 2
Now you'll be putting the laser of the thermometer on the exhaust headers where they meet up to the head so make sure you have a line of site to all of your header pipe ends. This works on manifolds as well but not as good. Its still the easiest way to find a skip either way.

Step 3
Now just locate the skip. To do that start the engine and quickly go under the hood with your infrared thermometer. Check each cylinder temperature, the cylinder with the skip will be cooler than the others around it. This works great because it will show you if you have a dead skip or just a cylinder that is running a little cold, all in a matter of mins. Information like this is very valuable for fine tuning and getting the most out of your engine.

Can an ERG valve cause my engine to skip


Usually when egr valves fail they cause a concern on all cylinders and do not cause a miss(skip) on just one cylinder. A miss is more typically a ignition failure.

Engine code: Misfire cylinder 1. Replaced plugs


There should be no built up fuel or oil in cylinder. The fuel will be burned off immediately, and there should have been very little unless you have a leaking injector. The only way oil will enter the cylinder is if you have a mechanical failure like worn rings or leaking valve seals.If after replacing the plugs and wires did not correct all or the skip after the first start up and road test then you have another issue causing the skip

How do you change an ignition switch on a 1974 corvette steering column ?


1. Disconnect Battery
2.Remove steering wheel 1 Clip then a size 13/16th Socket Clocked USE STEERING WHEEL PULLER FOR STEERING WHEEL 3. Use Steering Wheel LOCK RING Press Tool to remove it and its HOLD DOWN CLIP Horn Button & Spring will Come with it
4. Go to Lower Portion if Steering Collun and Disconnect and remove the BLACK Connecter that is Affixed to the Steer Collum
5..Back to the TOP Remove the 3 Screws that Hold the Turn Sygnal Assembly Down
6.Remove the Screw in the Center of the Hazaard Button
7. Remove the 1 Screw Holding Down the Turn Sygnal Lever
8.Now Carfully Pull the Entire Assembly OUT of the Center so as for it to be Out of your Way
9. Look CLOSLY at the Ignition Lock Cylinder Area and Locate Chromed Looking Button
10.. Push this Button While Slightly Pulling on the Ignition Key Lock and Remove Lock. NOTE If Lock seems th NOT want to come out you will need to Insert the IGNITION Key, But I Believe this 1972 Does Not Require the KEY

INSTALATION IS REVERSE PROCEDURE KEEPING A CLOSE EYE ON DETAIL. THIS SHOULDTAKE 2 HOURS
This is Off the Cuff as Most references DO NOT go Back to 1972 And I have Conducted this Procedure Literaly Hundreds of times

After about 8kms when the engine warms up the speedo & odometer stops working.... after cool down ... starts working again for a short time, ...suspect wiring problem in engine bay... any ideas


Wow... it's been a while since i've had the honour of working on a car like this! err.. One thing to note is that when warming a Mondial up from cold one of the exhaust pipes will produce more vapour (right hand side) than the other until the engine and exhast get up to normal operating temperature. This is obviously more noticable on cooler days, and is caused by the different lengths of the manifolds from the engine to the exhaust. This shouldn’t happen on a Mondial t due to the longitudinally mounted engine.
This can have a detrimental effect on the dials etc... check that the heat shields are intact and not missing! these produce a huge amount of heat... if they are missing ensure that the wiring harness is not damaged by heat.

Hope this helps

Changed out thermostat & truck is now skipping...????


Make sure that all of the sensors are connected.  Is the Check Engine light on?  Make sure that all of the spark plug wires are still secure.
What do you mean skipping?  Is there an ignition miss (e.g. cylinder not firing) or is the ignition cutting out periodically?
