the exhaust is restricted,,,,that means plugged..

Disconnect the exhaust before the CAT, and see if it goes any better. Hows the fuel. 1-1 1/2 yrs old. Does'nt sound good.

the cats are hollowed out wen i did that sum of the honey comb did blow out of the exhausht pipe could the muffler b clogged because of that? Oh and when i tried to accelerate it earlier it accelerated a little nothin major not even enough to move the car and the service engine light came on any more suggestion im out of ideas myself

[toddman67]

It is almost certain that the muffler could be plugged. Disconnect the exhaust behind the CAT. If exhaust can not exit.... It's like a pressure cooker.
Fuel pressure seems to be a big deal here as well. Look at the other threads. Get the readings and post. The guys on this forum are really sharp.

Scan for error codes. That should be a good indication.

rodents like to build nests in exhaust systems.
The cats were no restriction on the 4.3l.
Old gas can cause a LOT of problems.

A scan would pick up the low- and high-resolution crank pulses from the Opti.
