Truck diaognostics help please.
While driving my GMC truck around, i noticed it all of a sudden started to start lugging around. It has less power and i feel the engine/transmission shaking through the shifter while driving, and when i give it gas it sounds like my 69 when it had bad timing, it would be kinda of a slugging sound. Anyone have any idea? I havent looked at yet, because its night out but tomorrow i will, any ideas on where i should start?
Im gonna start checking the mounts, and instpect the engine.

catalitic converter might be clogged. tap on it with a hammer and see if your hear any rattling.

yeah, the motor is more or less choking. could also be fuel pump related.
