OK here goes nothing . I have a 01 tiburon rd2 and im having the exact same problem like 10 other people are having with their tibs . THAT STUPID SPUTTERING \ BOGGING \ POWER LOSS PROBLEM THAT HAS ALMOST MADE ME LOSe ALL HOPE OF KEEPING MY CAR AND HYUNDAI ITSELF. I have relatively small mods . CAI , 4-2-1 headers , cat back exhaust. the problem came on as just little miss and has grown to the gremlin that hides in my hood and giggles as i rage over the engine with every "repair" . Im pretty car savvy as i work at a auto body shop. SO FAR ive replaced the MAF , IAC , TPS , PLUGS , WIRES ,FUEL FILTER , FUEL PRESS REG. , 02 2X , O2 HEATER SIM BOX , PCV VALVE , PULLED AND POLISHED FUEL RAIL AND INJECTORS , ANS STILL IT COMES BACK !!!!. ok im calm. After about two hours of reading threads ive learned im not the only one who has to pull his battery cable to reset the ecm and it runs great. i can get to work and back before the CEL pops up and everything poo's out. MY question is : all the people who suggest to replace either, the camshaft sensor or the crankshaft sensor dont ever post back if that was is it or not. IM CHASING BUNNYS AHHHHHHHH !! CAN SOMEONE TELL ME IS IT CAMSHAFT OR CRANKSHAFT OR BOTH !!! I CANT TAKE THIS ANYMORE . PLEASE HELP ME OBI WAN HYUNDOBI YOUR MY ONLY HOPE......

Can you explain what was the rationale for replacing the parts you have listed?

 

Auto body is not mechanic work. Take it to a mechanic who knows what he's doing instead of just changing parts.

 

Those were the suggestions from two different mechanics not necc. in that order. OBD 2 scans just came up with sensor 1 bank 1 low voltage. I did take it to a mechanic and he said it was just the fuel filter.....wrong , $100 wrong .And as far as i can tell from other people posts is that they take it to a mechanic and spend lots of money for absolutely nothing. I just cant afford that right now either . Its probably about a horse a piece to have a mechanic look at it and hope he doesnt give you a line of b.s. than to hope and pick a sensor mech piece . I have voltage specs for all sensors and electric components and everything that we have graphed out on a obd 2 advanced scanners shows no abnormal voltages except for the maf .which i replaced . and no luck. what im trying to fig is what sensor to replace next. because either way it is electrical of some sort cuz car runs good until cel pops on then sputter city

 

look at packyred post on sputtering tiburon. sounds exactly the same and he said the dealer couldnt figure it out ? I have one last resort but it will be more than i want to spend , my uncle has a electrical specialized auto shop and ill prob take it there but with the economy being a turd there will be no discounts there
