Ok had entire intake removed , cleaned , new gaskets and injectors. Found a vacuum leak on a nipple at the vacuum box . At idle in closed loop ltft is now at negative 9. Idle still searching ,but not as often or as rangey. The roughness is less but norideable. Codes 0401 and 0442 . Thanks also...

I was referring to the slant on the letters changed midpost. Got brand new injectors and had them flow tested. From what I am reading ,factory flow rate is 230 cc/ min and thats what these tested . I am also getting an egr failure code. Would this cause the ecu to alter anything even though...

Did I ask an invalid question in the previous post?

Question concerning fuel injectors. I'm seeing them online listed with 4 holes as an upgrade from the oem 2hole . I don't see any afternarket 2 hole injector. Are 4 hole acceptable? Also could the thep0455 canister gross leak be contributing to the issue? This is a fairly recent code that has...

I am not sure. However I did listen to them with a stethoscope and they are all at least firing without skips. If injector flow rate is too large this could be why the way is having to max lean the af ratio?I'll order some new ones from a reputable parts house and get them brand new and take...

this is what I'm getting at highway speeds

here is the front o2 sensor after warm up. And etc reset. At idle. Smoke test done recently. Mods done about 4years ago.this problem was a fine one day and bad the next issue. Fuel checked at the service port. Injectors replaced 2years ago but they are remains from ebay ( yea I learned that...

this is what the map is reading at idle warm

Been fighting a rich condition for a year and can't find the cause. Mods: cai, egr delete, cat delete, oil catch can. 270,000 miles . Compression test done twice to verify 200 205 205 200. With the vss (manual trans)exception; all sensors fairly new and all pigtails checked. Ecu replaced. Fuel...

Yes I checked the map output with the engine just at idle using a backprobe and for some reason it's not a steady reading. Its almost like the manifold pressure is changing without the trrottle being moved. I will reset the codes and look to see what o2 sensor is doing . It's a fairly new denso...

Ok so I checked the 5v ref at idle and it was constant 5 .02v. However the signal wire back to the ecu is fluctuating at idle causing fluctuation that seems to correspond to the minor searching the idle is doing between 600 and 900rpm. Been trying to run this down for a year and local mechanics...

Thank you for the quick reply. Yes it's a new oem map. But I'm referring to the 5v reference signal through the pigtail. It's changing voltage without the engine running and just the key turned to the on position. I am having a rough idle with fuel trims showing -20 ltft and stft -3 using my...

97 eclipse original owner. 270,000 miles. Running incredibly rich. Mods are cai and egr delete . These were done years ago and car was running fine.sensors all new and all harness pigtails checked. The only one that is confusing me is the map sensor 5v reference that jumps around between 4.5 and...
