:Hi, I have developed a hesitation issue between 1500 and 1800 rpm's. The hesitation happens within the same range no matter what gear. I have done the following: replaced all injectors, all coil packs, all injector ends - tested same through harness at ECU. Readings were all ~ 12.2 ohms. Ran a Power Balance test with Conzult. I did this SEVERAL times. Each time, a different cyliner is showing up bad. WTF? I ran a compression check, all in spec. Tested the CAS and PTU, good.O2 sensors, good. Cleaned all ground points, and connectors on PTU, CAS temp sensor, and MAF sensors (both N62, both tested good). Any help would be GREATLY appreciated as I'm fresh out of ideas. Thanks!!!
Hi bro. So i read your post thats great u change everything but have u change your catconvertor or have them check ? i had to replace my 2 cats cause it was cusing hesitation. if u put your hand by the tip of your exhaust and u feel the air like blowing like poping air , then its clug, if it blowing constant air like u blowing air into a balloon then its good. u could test your cat at night by having someone rev the gas up til u look under and see if the cat gets red if it gets red then its clugging. u need to change them best change both. even out the power of air flow. i did mines it runs good. my injector was clug i use carbarator clean and spray into the injector direct into the intake pipe hose. and my injector kicks on. before was runing 5. now on 6. double check each coil pack plugs by pulling out each one while motor is on idle. u will hear the difference in motor. if it ducks of power then coil plugs works. if nothing happends then double check the wire with a wire tester to see if u getting power. i did that too. right now i think i lossing air from somewhere cause i not getting the right turbo pressure. but it still runs good so far do u know about the turbo pressure?
