yesterday i took it for diagnostics because of the check engine light. the p1128 code showed up. "Fuel Trim Lean Under Load". has anyone had this problem? i have checked online about the code. my acceleration is poor, my gas seems to get eaten up quickly, and on the freeway my RPMs rev at high speeds. need help ASAP

do you know if this is easy to install? are there chances if its installed i still might have the safe defects?

thanks

Hard to install not at all. Takes 5 minutes there are 2 clamps and 1 wiring connector if it was a wiring connector that was loose it actually give 3 codes so I doubt ithere is anyother issues besides the MAF not reading correctly. As for the MAF being $300 thats about what I paid both times. Theor the only parts I've had to put on either of those cars besides consumables like brakes and such or Maintanence stuff like timing belt/waterpump etc... None of the accents (All 3) have never left the girls or I stranded damn reliable...

usually its not the pipe it self but the 2 connecting its has to the exhaust manifold pipe and the rest of the exhaust if u look under ur car theres a small peice of pipe with like silver swirls wrapped look on it put ur hand by it with ur car running by the 2 ends of it and if u feel air pumping out in small or large quanties then go to a muffler shop and get it fixed

hyundai's are good at universal codes, my maf went out and all it said was a/f ratio was off, we tried the o2 sensors, we tried switching the cat, we tried 3 used maf's none of those worked, then tried 1 barley used maf and bingo, i can go past 75mph now lol.

with your maf if you want to try something you could buy some electronic parts cleaner...they sell it at napa and stores like that its in a airsol can and just spray it in the sensor and let it dry...take ur neg battery terminal off first though and put it back on when your done
