My xjr supercharged got about 5 liters of diesel put in from a jery can i had... Forgot it was diesel. Drove the car half kilomter to the bank and it died... So i had it towed got the diesel drained out the tank added new gas ... After 2 tanks of gas the cars know so slugish that it not performing.. I had the front resonator removed right after the cats thinking it was it was plugged.. But no luck... Know i feel it the cats r pluged

also dose that resonator effect the supercharger??

What do you think is the problem??????
Restricted performance light is also on.. Bank one & 2 too lean
also had a misfire 2,4,6

 

Oh dear....and welcome to the forum....

Running Diesel in a modern, fuel injected engine can cause all sorts of problems.

I'd say your cats, and probably your HO2 sensors are finished & will need replacement.

It would also be worthwhile cleaning your injectors, and replacing the fuel filters.

And change your sparkplugs. You should also change the engine oil.

Don't drive the car like this, it's not the sort of thing that will clear itself.

Finished as in clogged, blocked, stuffed, no good.

If you have blocked cats it doesn't matter how much boost you try & stuff in the engine, it won't help. Resonator or no resonator won't make any difference here.

You should get your injectors cleaned as well! And change the HO2 sensors.

When it comes to cats, no reason why you couldn't just get some generic 200 cell "sports cats" welded in. Would probably be the same cost as messing around with secondhand cats (which could also be blocked).
