MY 86 is missing really bad every time i leave a stop after it warms up a little. the timing is on i just but new plugs in the wirs are only a few months old.
the cat was clogged and i didnt know it for about 4 days after it stated running like . i cut it out and it still runs like .
i cant leave a stop without it studering and looking like an idiot.
if i floor it it will go but i dont like doing that.
when i am coasting the trans jumps around cause it doesnt now when to shift and the car shakes really bad.
the wires are on the right numbers.
any ideas?
im going to have it hooked up to a computer if my grandpas neighbor will do it.
A few things to look for:
Check your distributor for cracks and that the wires are well connected. Take a spray bottle with water and spray the cap and wires while it's running. Continue spraying each wire to its full length. If there is no stuttering you can assume that you have eliminated the cap and wires as being the problem. If you get stuttering you have found the location of a problem.
Take a propane torch (unlit!) and spray around all of the vacuum/intake connections. If you get a real change in speed you have found the location of a vacuum leak.
Since your cat was backed up you may have a lot of carbon buildup in the intake/EGR/etc. Try using some Seafoam pulled in through the brake booster line. Let it set for 10-20 minutes then crank it up. You should get a lot of white smoke.
You may have to pull the plugs and look to see if they are already fouled due to the poor running.
Good luck
MAP sensor vacuum hose. im going to replace it tonight and if that doesnt work i will try the MAP sensor
with hose on the booster? i need to do that to
long shot did your harmonic balancer fall apart? My 86 once did that and it shakes and shudder like a mother flubber.
