cat refurbish update
Might be too early but I have 500 miles on car and no 420/430 codes yet after I removed both cats and boiled them in citric acid powder solution for about 6-8 hours each...this is what I did in order:
new plugs new IMT o rings new air filter new upper and lower plenum o rings new throttle body o ring new upstream/downstream O2 sensors had 430 code again....then cooked rear cat first, then front cat put a can of BG 44K in gas tank to clean injectors So far so good...76,000 miles in car |
up to 1000 miles and no check engine light yet...but the wife said the battery light flickered on a few times so I bought new cables from Jagbits and will put them on when they come in--thanks Thermo for the suggestion...battery tested fine and alternator too.

I did the citric acid treatment to my front cat. I need to do it to the rear one, but getting it out looks like its not a lot of fun.
