SOURCE: Poor Acceleration Stalls at idle

Check the gas cap too. If the vent is failing, you will be getting a vacuum effect in the gaas tank. For every pound of vacuum, you will lose a pound of fuel pump pressure.

SOURCE: 2001 chevy blazer not shifting right

Check the oil if you haven't already. If that makes no difference, change the tranny oil and filter. It can make a world of difference. Another thing it could be is your fuel filter. The engine is starving for gas, and can't shift properly.

2003 blazer p301 code ive changed coil plugs check engen still flashing when accelerating

The flashing light means the problem is serious enough to damage the catalytic converter.
The code means cylinder 1 is not producing power. So it could be fuel, compression, or ignition related.

Problems with 2003 chev. blazer code showing p0601

Sorry to say the code is for an internal problem with the computer.
It could be a loss of power for the memory, or a faulty computer.
If it looses power, it has to relearn the basic settings much like a digital clock switching to 12 noon when you unplug it.
The computer gets power from the battery for the memory part and from the key switch for everything else.
The code will set if you disconnect the battery with the key on.

2003 Chev Blazer Service engine light came

Ok, first, you should clear the fault. Sometimes the system will get a bug, and there's not really a problem. You can do this by disconnecting the battery for 10-20 minutes. This will clear any faults. Next, see if the light comes back. If it does, then you can take it to get the codes scanned at a parts store(many do it for free.) Once you get the code and description, you have to troubleshoot the specific system that the code covers. The check engine lights are usually triggered by sensors going bad. On occasion, you will get an actual mechanical failure that will cause one.

This model explorer is equipped with a mechanical clutch fan. When starting the engine and when accelerating from a stop, it can tend to roar as the engine reeves up. If that is what you are hearing then yes, it is normal.
