Running Extremely Rich

[darkvader248]

Hey guy wats up I have a 97 eclipse GS-t and a couple weeks ago it started running rich with a serious idle problem (constantly bouncing).it also stutters between 1000rpms-3000rpm if im 50%+ throttle but once I am pass 3000rpm its takes off like a rocket and boost just fine, i also notice that my stock boost gauge has stop reading i dunno if that has any effect on how the ECU reads the A/F mixture.And my gas mileage has gone to shit im taking 150miles out of a full tank a gas.The CEL is also on and its giving out a Mass air flow sensor code but i don't wanna go pay $250 for a MAF and that turns out not to be the problem.

Help me out guys having to full up every 3 days isnt fun.

Maybe a bad o2 sensor?

If it's throwing a code, chances are pretty good that your problem or atleast part of it lies there.

[darkvader248]

i dunno i was thinking that at first, is there a way to test the o2 sensor?

[darkvader248]

and actually it shouldn't be the front o2 sensor cause its like a month old

Have you checked to make sure everything is plugged in? How about all your intercooler pipes, are they all connected and tight? Check to make sure all the sensors/hoses are connected, clear the codes, re-drive it and check the codes, post them here and I'll give you directions on how to test what codes it throws. Good luck.

ok guys i got a boostleak check today and it checked out fine cost 60 bucks those bastards, and the guy who did the dianosis said that to change the MAF sensor and see wat it does so i bought a used off my friend crashed TSI , so im just waiting for it to arrive in the mail

[gthompson97]

You paid $60 to do a boost leak test!? You can make your own tester for like $15.

thanks it was very helpful

[darkvader248]

unfortunetly i can't try it out cause my car is down again, i just recently installed a started because I assumed the old one was going bad, after the installation the I would had to crank the car a couple times to make it turn over, and then the next morning after the installation the car just cranks but never starts

can anyone help me on this one?

[gthompson97]

Did it throw a CEL?

[darkvader248]

nope but i actually just found out that the problem was my starter relay and not my starter which i literaly just already changed and it works great but the now i just gotta get the car to start. any ideas, the same old MAF sensor signal is being thrown which I got in the mail today just gotta install it and see wat happens.

[gthompson97]

Does it sound like it wants to start and just can't fire or is it just turning over and that's it? No chugging or anything.

[darkvader248]

yea it sounds like it want to start but just not firing
