I have a 93 4runner and its starting to get real slugish. I can't even go up hill, feels like its just gonna turn over and die. Also when I drive on the freeway when it gets to 55-65 mph its shakes and kinda stutters. Any ideas.

 

is the catalytic convertor original? if you get under the truck, and tap on the cat, does it make a rattling sound?

 

don't know if it's the same problem but my car got real sluggish when i lost coolant. how's the temp reading?

 

i had a similar problem, i dumped alot of money into it and got to the fuel pump and filter and it got better, not sure if its completly fixed cause i got it like it was 6 months ago
