My 86 Chevy Blazer K5 with a 350V8 has the check engine light on constantly.I changed one sensor on the exhaust which had a bad connection but no help.It idles irradically from high to low rpms.

Re: check engine light on

You have to get someone to use a scan tool to see what the code number stored in the vehicles computer.

Once you get a code number we can diagnosis the problem from there.

If you don't know anyone who has a scan tool you can go to Autozone or similar store to scan the vehicle for free.

They can tell you the code number and the problem area.

Get back to me with this information when you can so we can continue to diagnosis the problem from there.
car and truck information like nowhere else
