94 2.4L B23' lean bank 1
 

well ive noticed a loss of power on my 94 b2300 2.4l manual so i pulled codes and got 71/72... bank 1 at adaptive limits/ bank 1 lean, so i know on v-type motors bank 1 is on the #1 cylider side but its a inline 4, (Q#1)so how do i know which is bank #1 and (Q#2) should i be looking towards o2 sensor or injectors?

thanks in advance any ideas u may have

It's a generic code basicly. That engine only has 1 bank. Clean the injectors,replace the fuel filter,clean the MAF hotwire etc. If over 100k miles it is due a coil. Basicly a major tune is in order before replacing hard parts.

2.3L sorry was in a hurry... motor has 230,000+ but it still looks new, ive notice small cracks in the coilpacks (x2) but they dont spark in the dark and are $100 + each, im in school and will be getting a fluke meter soon, thanks for info, will pull resitances and stuff later
