Changing Spark Plugs, cylinders 3 and 5, 2002 year

I have a 2002 S-10 with 110,000 miles, 4.3L V-6. I was changing out the spark plugs and found that the access to cylinders 3 and 5 was EXTREMELY difficult. I finally, after several hours, managed to work through and change number 5. But I have yet to do cylinder number 3. The steering column seem to be right in the way. How do I access it?

Also, I periodically get a flashing "Service Engine Soon" that lasts for a few seconds (5 - 45) and then goes out. It occurs only at interstate highway speeds, and shows up after I have had to rapidly accelerate. Code tester shows no codes. Any ideas?
Do you

To get at no.3 you simply move the steering shaft. Moving the steering shaft only takes a couple minutes and saves a lot of struggling and busted knuckles. The steering shaft has one bolt at the steering box, simply loosen the bolt and then the steering shaft will collapse into itself and out of the way. It is keyed to only fit one way, so there is no need to worry about misalignment when reinstalling.

Or you can pry on the shaft and block with a piece of wood

Hope this helps

Subject: Thanks for your help on this topic
I guess I should not have treid to address two things in one post. Thanks for your help on the first one. Do I need to repost my second question into another post? I had asked about a flashing "service engine soon" light that comes on at highway speeds after hard acceleration and goes out in seconds.

I'll gladly donate again for useful help.

Sir

You can take it to autozone and get it read for free-everytime that light comes On or has flashed the computer records and stores it in the RAM section of the PCM. A receiving computer called scantool/code reader must be use to extract the OBD2 code/s to identify the problem area.

I should point again point out that my code reader show no codes. Of course, by the time I get home to plug it in, the flashing light has gone out. I have successfully read codes with the light ON steady, so I know the reader works. Can I plug the reader in when I am driving down the highway? The manual says to turn on ignition only, but DO NOT start!

A code reader and scantool performs differently. You might want to take it to autozone its a free service and get read.
