need some help here
98 taco 2.4l auto 125k miles
Few weeks ago i popped a P0420 code with no noticeable side affects
now i popped a P0171
When i start the truck it goes to a high idle...1500 rpm
When truck gets to operating temp it drops down to a low...500 rpm
dont think its the MAF i cleaned it really good
My truck is low low low and i scrape the cat heat shield like everyday
Im thinking i may have an exhaust leak
How bad could it be?
If i need to have exhause work done i was thinking about raising the cat. Anyone ever done this or know how difficult it would be?
Appreciate any help (CT is pretty much dead)
