Still having problems....
Ok have had the car for over 6 months and still same major problems. Mechanics have nickel and dime me to death with this thing I'm well over $2000 deep into fixing this thing. Its a 98 gt vert.
What Happens/ed
Car runs fine then either from startup or while in the middle of driving it, it will start to buck/miss fire really bad. Its drivable to get home as long as your not too far away. When i replaced the Maf a few weeks ago it ran fine with a very small miss for about 2 weeks . Then all of a sudden while driving home from work it started to do it again. I then replaced the Maf again and it went back to bucking and miss firing.
When it happens:
Runs fine at idle
Runs fine when floored
Problem doesn't happen all the time (after about 5 min of driving)
When I replaced the Maf the first time it ran fine for about 600-800 miles
Changed oil smelled like gas
Replaced:
Exhaust and x-pipe
maf 3x
coilpacks 2x
plug wires
spark plugs
fuel pump
fuel filter
changed oil
computer
codes:
lean on bank 2
o2 sensor
Possible causes????:
fuel injector?????
Pinched wire???
vacume line?????
please help with any ideas. Ive read recently that injectors that are bad make it run like im discribing and they also pull a lean on bank 2 code. so im wondering about that. i dont have any volt machines or anything like that so how would i check the injectors ?

gotta go back to autozone to check it later
yea i was thinking that one gets stuck shut when driving that way it acts. yea i know the o2 sensors are bad but i was being told it shouldn't effect the car to much.
It is possible that one or more of your fuel injectors is clogged.
One or more of your front or rear 02 sensors could have failed.
Also if your mustang is running on a lean condition then I would
definitley consider purchasing a programmer and getting your mustang
tuned to correct the A/F ratio.
