bogging and stalling

Ok guys I have a 91 Mazda b2600i that's bogging and stalling so I've put a new fuel pump and filter,spark plugs,plug wires,distributor capand rotor and my truck still bogs down while driving while stoped at a light it will stall. I've also checked the timing the fuel filter was really dirty so could the fuel injecters be clogged or what I'm stuck. Thanks in advance For the help

Dude, I had the same problem with my 86 b2000. Come to find out after having the carb rebuilt and resetting the timing it was the cat convertor off the manifold that was clogging up creating back pressure in the engine causing it to bog. i took it out and jammed a prybar through it shattering the honeycomb giving it direct flow and no more bogging.

Pulled the cat and still have the problem thanks though

could be a clogged jet in your efi. but i dono i havnt taken that part of my automotive class yet. but i would run carb and fuel injector cleaner through it.

Got her running good now had bad gas tank now its time to start mods thanks for all the help
