So - I just got a new cat installed to pass my emissions test and get my red baron (92 XJ with 98HO) back on the road. Now - I've been having some problems with my fuel gauge reading artificially LOW for some time... it was consistently reading about 1/8-1/4 tank lower than was actually in there (better than the reverse I figure!) but since getting my new cat welded on - suddenly the fuel gauge is not only reading much lower but being really inconsistent. And now so are my BATT and OIL PRESSURE gauges. My best theory on this is that the welding wasn't done properly (no battery disconnect?) and it's somehow messed up the gauges directly or messed up the ground reference for all gauges.
So the question is - what can be done to reset my systems ground for the vehicle (and gauges) - SHOULD that be the problem (or else - what CAN the problem BE?) - AND what about the fuel gauge? Could the 'offset' have been due to a similar problem or is it just the death of my sender unit (that's PART of the fuel pump from what i've read??)... thanks much.
oh - one more thing - as a random topic... since the new cat was put on - suddenly i'm lurching and hestitating when on the freeway and I try to give it gas wide open. I'm guessing it's due to the narrow (low flow) cat in the middle of my high flow exhaust system and borla headers etc (?) - or should I look elsewhere and it's a random phenomenon? (or maybe it's related to the gauge problem above??)
