Chevrolet Blazer has no power and engine bogs down
In the morning I'll drive the car and it will be fine but wheni park it and come back to it later for lunch i have no power at all. The engine bogs down when first driving. I'll have it floored for a little bit then out of nowhere i get power. i have changed all the plugs, wires, distributor, cap, fuel filter and pump.. I'm out of idea's. It also has a rough idle if that has anything to do with it. People have said it may be a clogged cat converter? any ideas? Thankss

Both of these problems have symptoms you've described. The first (Mass Air Flow) is located on the air breather intake (looks like a honey Comb). If not that code then your problem is most likely the cheap plastic distributor that GM installed for that year. Take off that expensive cap and see if the shaft jiggles. It is better to remove the distributor to inspect it. AutoZone sells a lifetime warranted Distributor for about $90.
I have seen two different cars just recently where batteries less than 90 days old have shorted out. Somebody (there are only a couple of companies that make batteries, they just change the labels for the different brands) is making junk batteries. I use Delco and have had no problems, Interstate seems to be okay. The bad ones were both from AutoZone.
We are going to ask you a stupid question, if you don't mind? What would MAF mean? We're not sure of what that could mean. Let me know. Thank you.

We don't have a MAF problem. Lets do this, go back and read all of my post that we've put up and please, let me know if I may have not went into depth about. We really need some help with fixing the issue that is at hand. Please, help, if possible. Thank you....
In addition, anytime you hit the gas to accelerate the RPM gauge suddenly shoots up to 3.5 and shoots back down to 2, and keeps going up and down until you let off of the gas.
Starts right up. New plugs and wires. Never really cuts off. Runs hot but not extremely.
Thanks for the help.
What is the scanner showing happening to the fuel trims and oxygen sensors as it's running under these conditions where it starts to get bogged down? What's showing for the engine coolant sensors?
Going to need to go to a competent shop to analyze what's happening.
