i have an 86 na that just recently bit the dust. I was leaving my girlfriends house, when all of a sudden my motor strarted to sputter and lost most of its power(i could only do 60 on the highway Floored!). So i did most of the usually thingsplugs,wires,cleaned all 4 injectors,and so on. All of this was to no use for i found out that only my front rotor was working, i am getting spark from all coils.
please help as i am an experienced piston mechanic but novist with rotorys.

 

Is this a question? Do you need rebuild help? Are you asking how to get power back to the rear rotor after its obviously gone?

 

Get your compression tester out, remove the check valve, place it in each upper plug hole, pull the EGI fuse in the engine bay fuse box, crank her a couple of seconds each rotor, and report back with the readings from the 3 pulses from each rotor...

 

did check it was 90 -120 psi

 

was there 3 pulses?

 

i did the test earlier and did not know about the three pulses,
the car will not start with just the rear wires hooked up unless i use eather and then it dies.

 

pretty sure it's a bad apex seal, but if you can find out for sure that there were 3 pulses than we will have to look elsewhere...

 

one more think when i pull my plugs there fouled with oil every time even after 5 min?

 

when i pull the rear plugs there fouled with oil no gas/i have a A/F gauge that is reading lean

 

well I have an 86 and I recently blew an apex seal due to a bad injector, so it ran lean and popped the seal. When I removed the plugs they were fouled with oil as well, perhaps something to do with improper combutsion due to the lean condition? I don't have an answer for the fouled plugs myself. But perhaps the best thing to do is find out if there is three pulses, and check out your injectors.

sounds like a sensor..........

 

rebuild time, that exactly how my 88 SE is, good compression on front, none on rear.

i have a 88 FC3S no tittle with 30k mile 13B in it if you are interested in buying it i will help you out and let it go for $700 and 90 day warrenty so give me a reply and let me know if you still need it since sevenstock is coming up would let it go for less if i could but i have tickets to pay for toying with the local cops here in mobile street racing

iwent out this morning and tested both front & rear comp. 3 PULSES.
dose this mean good apex seals both were 95 on all three pulses>

 

yup, time to start looking for something else causing this
