Reply With QuoteI am stumped as much as you are Matt.
Did you check your entire fuel system (pump, lines, filters, regulator, return) to see if there is anything related to your possible lean condition?
damn kid. Well good luck...I am sure that if you are taking it to Art he can figure it out

clean the injectors?
i ran injector cleaner on my old motor with the old injectors, blew the motor the next day...maybe had something to do with it? idk....Originally Posted by Blue Ice
truthfully i havn't really thought about it on these "new" injectors that came with my "new" motor. good suggestion though...i'll bring it up when i take the car in. i'm done with it for now, i can't bear to look at it anymore, i've been living under the hood for the past month
kimya good call on taking it to arthur, will talk to him today....
what blew your motor? i doubt injector cleaner can blow the motor.
i still have yet to pull my old one apart and look at it. no doubt the lean condition i'm suffering from now had a lot to do with it before.... i've been so busy trying to get this one running right so i'm not just swapping engines every 6 months i havn't had a chance to look at the old one
basically my old motor crankwalked; when i pushed in on the clutch, RPMs would drop considerably, and the engine would be shaking and vibrating when i gave it any heavy amount of throttle
just got back from a trusted mechanic (arthur) and told him my whole sob story. basically he wants me to replace the pcv valve, thermostat, and get the injectors cleaned before he takes a look at it. said the ECU is also a concern since they're weak on the 94s (big surprise there *rolleyes*) he knows mitsus and drives/owns the starion that won at MOD a couple years back
ok i'm being lazy and didn't chack to see if you mentioned it before, but are you running both O2 sensors the ECU looks for? Pre cat and Post cat. and then have you check ed the wiring and condition for both sensors?
yeah, both O2s are brand new. i know the wiring is legit, i dont know what you mean by checking the condition though. i mean the narroband a/f is basically a visual voltmeter...
so do you know anyone that has a fuel pressure guage they can throw on it??? that can tell alot... i asure you if your fuel pressure was anywhere near 0 psi the car wouldnt run... lol alot of cars can end up in a crank no start over 5 psi!

i've been running my old aeromotive AFPR with gauge. set to factory spec, fuel pressure is normal. guess it's not fuel pressure.....
Id try another ECU, maybe send the injectors off to get cleaned and flow tested. I dont trust injector cleaner.

there is one more thing to check with a fuel pressure diagnostic guage... with the car running you should be able to press the button on the side (i am aware the aeromotive fpr wont have this) and get about an ounce per second out of it... this is a rule of thumb for about any port injection vehicle... if its way low from that its your filter, pump, or both... if thats good then its injectors or tune..

i installed a new PCV valve tonight, new thermostat going in over the weekend, ordered a "new" ECU off ebay (same part #), sending the injectors off to RC in culver city to get cleaned ($24 per, ugh).
after i do all of this, if nothing's changed then when the motor blows i'm getting a new car.
which really makes me a little sad realizing i'm not that bummed......
lol man the sad truth is its a mitsubishi, and i love them to death but they can be a real headache!!!

dibs on the G's carcas.
As far as the o2's. are you sure the wire for the front o2 is connected to the front sensor, and not have them switched backwards. i'm sure the readings are different. you might try switching the wires around just to see. Aren't the connectors for both side by side on the intake manny?
lol DAMN dude, i would have to be so retarded to switch the rear with the front. maybe on your car it's different but the rear o2 is post cat for me, and the wiring for that one goes into the body of the car right next to it. the front o2's wiring goes straight up to the clip by the fuel injector rail.....switching these two around would require some serious stupidity
oh and believe me, i'll have a field day parting out this car lol
god...I remember when this car was green! Don't let it go...put it on the shelf, get a daily and work on this when you have time
"Why fart and waste it when you can burp and taste it!"
Its just a car, its not worth the headache if your current solutions don't fix it, Sell it and buy a BMW ;)
And its not the o2 sensor. If the front o2 sensor was bad, the ECU would run in a limp mode which is a predefined map in the ECU and is richer then normal I do believe.
7g for life!
