ok got off the freeway last night and looked at my exhaust manifold glowing bright red....... i'm thinking a plugged cat but then again it could be something else.... any help is greatly appreciated

 

could be the timing or knock senser is not doing its job.

 

how was it runnin normal or rough at idle and up to speed and was it low in oil?/

 

runs pretty normal and has plenty of oil

 

ok heres what ive done so far...... i made myself a custom high flow ghetto cat... aka hammer and a big pry bar (that stuff comes out easy) this is temporary ( in case someone here works for the c.a. dmv) till i upgrade to a header and new exhaust. i am thoroughly convinced that K&N filters suck the tube that goes to the plenum was filthy also the stock airbox was digusting i took all that apart and soaked the parts (not the afm) in degreaser and they were spotless when i was done i will be doing the seafoam treatment tommorow in case my injectors are not closing properly so i will see if it is better and report back

 

Those old skool cats suck. I got one of the new "honeycomb" style hi-flow cats. Supposdely they are better with emissions too.

Good luck, curious to hear how the seafoam works for you. I couldn't find it anywhere around me.

 

i drove it to work and it was still really hot so ???????

 

Did you try NAPA, Seth?
I think the part number is SF41 or something like that. I know the first 2 are SF and the last 2 is some combination of 1, 4, 6 - I think.

 

Yeah I went to 3 napas, they all said they carried it, but have been out everytime I go by. I'll keep trying

 

sounds like its runnin lean

 

my motorcycle did that
