I tried cleaning it, tried replacing it. same result.
lt ftrm1 -1.6
lt ftrm2 17.2
st ftrm -23.4
this part of the reading I got makes
me wonder why the lt ftrm2 is
high? I've tried researching it but so far havent
found any info.
Check for a vacuum link related to the PCV system. They are
prone to cracking and clogging with age. Pay particular
attention to the elbow located near the throttle body. It
is probably best to go ahead and replace all of the soft
parts in the PCV system as they are difficult to clean once
they began to clog. It is possible to clean the metal
fuel pressure reg. maybe? it has had pcm replaced with a junkyard unit
year ago, any chance it could have same issue with this one? It
although very bad with the maf unplugged, as soon as I plug it
back in it starts
to run rough, very rich (black smoke and lots of it)
and misses badly then cuts
off. I tried a new maf and no difference. Any
good ideas would be appreciated.
