Oh where to begin ...
Bought my 95 talon about a year ago and have done all the maintenance I can reasonably think of before upgrading. I don't drive it much (probably 200 miles in the last year)
Compression ~180 across the board
Maintenance:
Belts, pulleys, tensioner, oil
Before upgrading its was near stock condition and ran well; 15psi on t25.
Upgrades:
Evo B16g (wg pressure for now)
RC 550 Injectors
Evo 8 ECU (EvoScan and EcuFlash)
AEM wideband (installed rear o2)
Boost gauge
Oil pressure gauge
Injen intake
Walbro 255
AEM Afpr
EGR Delete
Charcoal Canister Removed
Crushed 1g BOV
I got the car running and went to the gas station to fill up the night before tuning. Wake up the next day and car won't start. In short, injector scaling was off and it fouled spark plugs. Got it running again and took it out for a short drive, I heard the pump start to whine (loud) so I drove home and called it quits. Next day it wouldn't start again, so I thought the plugs were fouled again, but no luck. It turned out that when I filled the tank up with gas (full) it grabbed rust from the rusted out suction unit and pulled it to the sending unit side. This went up to the fuel filter and blew the internals of that filter out and clogged up my injectors. Who would have thought, rust in a plastic awd tank.
Maintenance #2:
Cleaned Rail w/b12
Cleaned injectors w/b12 (9v battery etc.)
Ran pump (evoscan) to filter to flush out line
Cleaned filter to rail line w/b12
Installed new fuel filter
Installed (New looking) suction unit
I noticed a rust like coating on the walls of the plastic tank.. not sure if that is normal, but really didn't want to drop it. I did pull most of the visible particles out. I'm ok with changing the sock or filter.
I have gotten the car running again and started to get the base tuning loaded. The car runs rich ~10a/f at idle with injector size at 513 and scaling at .180ms. I can adjust the size up to ~3000 (yes 3000) and it will help bring it up to ~12a/f, but I know that's not the correct way.... I have noticed that the walbro pump will progressively get louder with the size at 513 and it doesn't at ~3000 which is weird.
o2 sensor is reading .9 volts (will drop if I give it gas) - already replaced
STFT -25%
actuated injectors (while idling) and could tell each one was shut off
Things I think are the culprit:
Injector scaling is off
Injectors are leaking and I need them professionally cleaned
Boost Leak? I haven't done a leak test
What else can you guys think of? I could use the help.
Thanks
