Bad. He said the cat was empty. I suspect that the cat insides caused a clog which in turn increased back pressure which caused other exhaust leaks. It does seem that there is ample exhaust out the tail pipe. ?? So I don't have much money and am looking to get back on the road. At present it takes about two miles to get the truck up to 45 mph. Low rpms only. Running very rich. Thought of changing the O2 sensor next to the repaired manifold but hard to get a wrench on it. Odd that the cat ran much worse immediately after the repair. Scan just show multiple engine misfire but I've got an old computer in the car and it does a few goofy things with the dashboard lights etc. I took it to Midas and they wanted $2100. Can't do that. What would you do?

Hi John. It’s quite possible that the source of your Infinity issues is something simple (like an O2 sensor) or major (such as a catalytic converter that is worn out). The best way to pinpoint the precise source of the issues is to have a professional mobile mechanic complete a car is slow to accelerate inspection, so they can accurately determine what’s causing the symptom and recommend the repair that should resolve the problem’s you’re experiencing.
