How's the EGR valve and how old is your cat?

In my old car, I used Mohawk premium (an empty tank then add 4 litres), then add a litre or so of Methyl Hydrate and some "sure pass" form crappy tire.
After Aircare - put in more gas right away.

the cat is about 4 months old, from kinetics when they built the full 3" catback .... as for the egr ... i have no idea.  how would i check this?

hey thanks marty, i did what you suggested ... and i passed! before my hc was 169, this time i got 80    .... but i overlooked a step.  i have yet to fill up gas after aircare.  i drove straight home after i passed.  will the MH do anything to my car?  i had about 5 littres of gas from petro canada 94 octane .... then i went to mohawk and added another 5 littres of 94 ... and 250mL of MH.

Ah, good old chemistry eh.....

MH in large qty make the car run poorly and is not fabulous for it - but it will not kill anything, you did not put much in.
