this is a how to, to see how to figure out if your catalaytic conveter is clogged,
1st, pull the o2 sensor the one on the rear exhaust manifold
2nd, then take it for a ride with it out
3rd, if you have your power back this is your problem,you need a cat
4th,go get / buy a cat
5th just cuz it dont make any sounds wen you tap on the cat does not mean its good, and it will not be glowing red thats only if its not runnin rite dumping raw fuel in the converter
might be not be amussing but will help alot ppl out ive been doin it this way for over 12yrs now, im a ase certified mechanic, using a back pressure tester half of the tyme will not tell you if the cat is partially clogged. i hope this can help alota ppl out , pic below was my partially clogged cat would not excelerate and was bucking and had all cylinder missfires data codes p0300
