Trouble keeping 91 NA started
Running a 91 RX7. NA. 13b.
Has headers, emissions delete, electric fan, oil metering pump delete.
Has a K&N filter than you need to oil.
The L igniter wasn't sparking, so I bought a new one. Now getting spark on all 4 plugs.
Also changed plugs out to new NGK coppers. (The one for rotarys. I forget the model number)
PO ran car through a car wash and we're assuming it fried the igniter.
Car throws a code. "11" Which is the thermosensor, I believe. Thermosensor has been changed out.
So my issue is, we can get the car running, but in order to do so, we have to disconnect the afm and artificially create a rich situation by blocking off the intake.
The car will fire up and we have to gradually introduce more air. We can hold the car steady around 2,400 rpm. If we drop it down, it will stall out, if we go any higher, the car looses power and we assume it's leaning.
If we reconnect, the afm, the car will will fire up but not stay running for more than a second or two.
Is there anything else that may be causing this issue besides a bad afm?
