that is a new maf i put , the one that the car brought when i got it was so so.. It turns on but does not react as good as when i have the new maf connected

trxrx7 · 03-26-2013, 06:53 PM

sounds like maf, disconnect maf and see if idle changes

OrangeVirus1 · 03-26-2013, 07:08 PM

maybe the headgasket blew while it was stored.... :P kidding.

archonftw · 03-26-2013, 07:27 PM

clean maf with maf cleaner. if you take off the maf and move it around when you put it back on it'll most likely work, but after awhile it may start doing it again.

maf wiring could be bad. could be your fuel pump. could be a lot of things. check everything.

Did you remove the dizzy? Check your timing. My car ran like shit but idled fun and my distributor timing was off.

boostedk · 03-26-2013, 09:38 PM

new spark plug cables , new rotor and roter cap from the dizzy , im leaning more to the fuel pump i dont think its good

second_chanceS14 · 03-26-2013, 10:06 PM

boostedk · 03-26-2013, 10:08 PM

yeah man, shits probably not pumping enough fuel. Also make sure u checked your injectors

Rb26kouki · 03-26-2013, 10:14 PM

Definitely Fuel PUMP!
Just get a Walbro, it will be good for feature upgrades.
make sure you get a authentic one, buy one from a authorize dealer.

Lumos · 03-26-2013, 10:23 PM

I had a similar problem when my battery went bad

ocn · 03-26-2013, 10:27 PM

fuel pump .. i had the same problem with my sr till i changed the pump to a walbro

91rps13 · 03-26-2013, 10:51 PM

have you read the trouble codes??? Seems like check engine light is on, just use a scan tool and go from there.

godrifttoday · 03-26-2013, 11:09 PM

Sounds like maf to me

curo72 · 03-26-2013, 11:48 PM

It's for sure the right maf sensor?
Bad gas? The car has been sitting for a couple years.
Fuel filter?
Have you gotten the codes scanned? If not, that's definitely the first thing you should do.
