Question about 2001 Chevrolet Blazer
I changed the spark plugs and wires on my 2001 Mark, and it was running rough, so I called around and finally spoke to a mechanic, and asked the same question, he must have put me on speaker and requested me to repeat the question, I heard the shop burst out laughing, the computer sets the timing on these cars I was told. But what happened was that the wiring was dried out and needed to be replaced, after I pulled on it and such. Maybe its your wiring?

The color codes will be different so when you take the harness off the 95 make sure that you label ALL the connectors to make it easier to install it on your Blazer. You may also have to change some sensors or switches up to 95 so that the harness will fit. Label all the empty connectors with their location in the 95 because they will be for options that may or may not be on your Blazer. If you have to access a wire diagram to complete the job then use the 95. DON'T let someone else take the 95 harness out for you andtake a rough diagram of your truck with the plug-ins marked for location and # of pins for wires. Basically it should fit but attention to detail is a must.
Also check out faxonautoliterature. They list GM service manuals but also GM books for engine interchanges that may prove to be very helpful. Hope this helps.

are they buying south of the border pumps from autozone or places like that or are they quality ones like NAPA?
Another reason might be are they installing a new screen sock on the new pump or keep using the original one?
and the last would be if you are running on almost empty all the tome,the gas is what lubes the internal bushings

Do a compression test on all of your cylinders when it is cold. Backfiring is a sign of a worn valve seat allowing mixed fuel and air (lit by spark) to be forced back into the intake. You will probably see compression loss on one or more cylinders.
Also... there is a chance that the EGR valve is not totally seated when the engine is cold with just a small blow by. The EGR valve seats coke up over time with black gunk.
