Stock s13 SR blacktop stock internals
Okay so i was tuning on my AEM stand alone and did my own tune, had a good street tune everything was running great. I never ran lean. I went about 250 miles in one day everything was good.
I converted to MAP to use my ems by the way.
Then i set my limiter to backfire and spit flames at around 5500 rpm for a few revs because some ricer kept revving behind me at a meet so i attempted to burn his bumper.
Then cylinder one started clacking immediately (hard to explain) so i shut off and started 30 min later and the clacking stopped but i was running on 3 cylinders.
With my laptop out i turned off cylinder ones injector and it ran the same nothing changed. But at slight revs it would ping in cylinder one not knock just quickly ping once everytime you give it a little gas. I could drive the car like this but obviously wont. It was running idle at 2k rpm and rich about 10-11 at idle on 3 cylinders.
WHAT I TRIED:
Checked if my spark plug broke off into the cylinder and it did not.
I set my ignition back to stock on the computer and it dident change anything. I check my ignition timing with the light and its perfect. Did a compression test and its good. Leakdown test cylinder 2 has a slight leak. i swapped around coilpacks and the ping still is in cylinder 1. pulled off fuel rail to see if any would leak when the pump primed and nothing came out. Nothing came out when cranking either.
In attempt to see if my tune was the problem i put back in my stock ecu, plugged the maf back in, changed the stock cas disk back in. Unplugged the map. Put everything back to stock.
Then i tried starting it and it wont start at all anymore. It cranks and sometimes black smoke will puff out the exhaust and sometimes white smoke. i let it sit for hours and tried again and nothing. This is how it currently sits.
I have not yet tested my spark, cas, ignitor, or coilpacks beacuse of the fact it was starting fine on my tune.
If someone has some ideas to check please let me know!
