car ran fine last night(had empire over) for 10 minutes.
would be rev happy.
at the 10 minute mark cyl 4 losses spark.(like clockwork)
at the 11 minute mark cyl 3 losses spark and car dies.
waited 10 minutes.
car started perfect would idle (wouldnt really rev without a backfire or 2 thinking the o2 is bad...) but it would rev.
10 minutes on the clock losses cyl 4...
11 min cyl 3...
did it 4 times in a row.
today i tryed to start it at about 1shared_pm. started but couldnt get it to rev well atall.(had to floor it to get it to move 10 feet... and even at that i barly got it to move)
empire and i went threw the book and tested everything. nothing looks out of order atall.

 

coil pack

 

how would it be coil if it is always cyl 4 and only cyl 4??? then a minute later cyl 3 starts to miss a fire ever other fire...

 

well start with the basics change out
spark plugs
wires

 

done and done... i have covered the basics weeks ago... i have done everything but replace the motor...
empire came over and did the same thing...
its at a repair shop now. there saying the distrib is bad(my dad brought it there and is paying for it to be fixed before i can get it back to work on it some more)

 

Thinking it is the distributor. Its obviously spark related.

Assuming you replaced the ecu? Checked all wires?

 

any update?

 

how much does that shop charge to replace the distributor?

 

if you are dropping a cyl after warm up, it is actually the pickup plate in the dist. There is a 720 fine tooth plate that runs through a optical pickup inside the dist... just like a cam sensor on a SR. This is happening on a lot of SRs / KAs with age.
