It accelerates very slow but will rev to 7000 whats wrong



need info



It's a 12a engine help

 

doesnt sound too good. before you do anything check the compression.

check the faq section for a sorta how to.

 

I've got the same problem, but my compression is good. I'm thinking that it's either a clogged (or starting to clog) cat or a carburator problem like clogged jet, plugged fuel filter or else the secondaries are not opening. My idle is also a bit rough and i've got a small back fire when I shift. I will respost when I've figured it out.



Good luck to both of us.

 

i'd start with checking the igntion system ( coils, distributor,cap, etc) then your pump and fuel filter

 

Did you check the compression 84rx7? A bad apex seal will cause the engine to have little power under load, but still be able to rev in nuetral. You will also have a rough idle if the engine can even keep one.

 

that's happened to me last year.after too much searching i found that it caused by bad spark plugs.try to replace them.that was saved me.please let me now if it helped you.

you also may have a flooded motor,then you have to try the ATF treatment.

 

If it's the cat they will usually give off a nice red glow, just check it when it's dark out!
