Hey I'm kinda experiencing something really strange on 03 track
I can't tell if its the throttle body or the pedal which is really weird....
I floor my car at 1k 2k 3k rpm it goes but then at 3.5k or 4k it seems to bog (sluggish) down to the point it where it's not even picking up at all. I bought a new maf for it n didn't do anything. Put fuel cleaner didnt do anything n I also changed to the battery. It does this in ever gear
What could this be??? also it seems when I do the throttle body value reset which causes the car to go back to Normal but after second time starting it later it just starts messing up again. It's driving me crazy and I can't figure what the cars issue is, cause I just bought it from some kid like an idiot. He didn't really take care of it but it wasn't doing that before I bought it. But two days of driving its just started being really sluggish.
This also started as soon as I bought some led tailights from eBay but I don't think this can be the issue.... Also when I first try to start the car it doesn't crank. I have kick the clutch pedal really hard couple times and then it starts. I'm really tired of putting money into this car. Please let me know if you know what it is or if you experience the same issue. Much love
Sry for the grammar it's 5 in the morning and I'm tired of working on the car.

 

Oh btw car idles just fine. Revs good in neutral, no engine lights or anything.
Just seems really sluggish. Can't tell if I need a new throttle body or I have a bad wiring. Idk Also I alway put 93 in it.

 

Before you throw any more parts at it, have you pulled any codes on the Z?

 

Could pull codes even if the engine light is not on?

 

Yes you can still pull codes!!! The damn engine light only shows when parts go to a point it just stop working! But when it still works there aren't any CEL!

 

Thanks guys I'm getting it checked out Nissan right now and well you guys know what the issues is

 

i have a feeling it had a messed up plug, my rx8 did the same thing after i picked up some water and the plug still worked but not as well

 

Then you bought the wrong car.

 

i dont need your stupid f***** input about what i bought
i didnt ask if i bought the wrong car i came here to see if someone had the same issue and if someone could help.
i hate people like you so ****in negative and always got say something stupid

 

so i took it to nissan and they didnt know what it was either i paid 120 for something that have all the computer in the world of what it can be but can bottom it down
im starting get worried it can be the fuel pump of the i might have to change the manifold to the stock one or i might have to change the throttle body. mean time I'm going change the sparkplugs and hope something happens i will keep you guys updated
thank u

 

could it be the ecu is defective or modified? can it be reset or tested?

 

It's your ebay tail lights, They make the ECU think that you are braking while you are not, Common issue with many nissan cars.

Put your OEM lights back on.

 

thats the thing when i reset the ecu or do this thing called throttle value closed position it runs okay until i start the car the 2 second time. but also when it has low fuel it doesnt do it as much but it still boggs but not as bad

 

i agree that for testing purposes, switch back to stock tail lights to proceed.

ok but it still might be bad. that's not the reset i am talking about. i mean reflashing a stock program.

 

okay im going try putting the oem taillights back on and see what happens
i will let you know if this does anything at all
also im sorry do you know how to reflash it?

 

thanks man im going try it tomorrow

 

Sooooooo i replaced the taillights with oem ones and it runs sooo much better
thank you to everyone for response on the thread i really appreciate it
i wish i would of done this in the beginning but im glad i didnt keep dumping money into it!!
much love everyone and dont buy parts from ebay

 

Just for next time, not trying to be mean or anything but if your looking into a mod do a ton of research on what part your putting into the car so something like this doesn't happen again. I remember when I was researching aftermarket taillights I found a lot of people complained about getting the same problem you did. Mod carefully and don't cheap out. Do it once and do it right.

 

wtf eBay tail lights no way

 

Lighten up, Francis. I'm just ribbing you. Everyone knows that this car isn't cheap to maintain. I've done a lot more to help people on this board than you most likely ever will.
