RB20DET_Silvia

When i have reset mine i just take my car for a good ride start of slow then give it some. and seems to do the job. first time i reset the car i noticed a difference. - Luke

I have spoken to my mechanic he said he thinks it would be my spark plugs.....he also said am i getting this misfire and etc through out the whole rev range im like nope he said well it wont be your coils as it would cause rough driving the whole time not just at high revs, if it was the coils u would know cause u would get rough drive the whole time due to one not causing any or enough volts to ignite the spark plugs. He said buy or clean spark plugs and get new fuel filter and then go from there. Dead coils would cause rough ride the whole time. - Luke

I believe if my coil packs were stuffed it would run rough the whole time i drive the car. This does not happen, it only happens once i start to really push the car at high revs as stated above. It runs perfect normal driving and through out the medium rev range just not the high revs. I might try cleaning my spark plugs and getting a new fuel filter any other comments anyone. - Luke

its not a complete backoff its just like misfire....like u can hear the engine still going buts it just not moving any faster then it might start climbing up the speed then starts the misfiring sound again. - Luke

Can anyone help? - Luke

Hey guys when i really give it to my car it starts to gurble and burp i hear the engine going but cars shutters and does not move any faster will that be the fuel cut or will i need a fuel reg it has a new fuel pump and has the speed limiter still? If i turn the car off and leave it then turn it back on if i smash it straight away there is no problem but after that little bit of smashing it gets back to its habbit. I really need to fix this as my car suffers so much if i cant get all the power. I have a RB20DET on 13psi in a silvia just to let u know when there is no fuel cut my car flys like shit out of an ass but with it on it sucks balls on 10psi it has the same issue. I could not tell u at what revs this is happening as rev meter dont work. What do u think the problem could be. and how would i got about fixing it. Thanks guys. :Pimp2: - Luke
