B18c1 fuel cut at 3k and car dies at 5k???

[gsrhatch]

Ok i think i might have a serious problem

First of all id like to say thank you for looking and helping if you do

Its an Eg hatch with a 99 GSR motor.. stock head stock bottom end just has full exhaust and intake

I havent driven the car much in the past week cause i was afraid it would keep happening. But the 3 days i have driven it recently , it has done it every time.

In 1st ,2nd , and 3rd gear at about 2000-3000 rpm the car starts sputtering and at 3000 it acts like its hitting fuel cut or im mashing the gas then letting off completely and itll keep doing this till i push the clutch in rev it and take off again. Also about 3 or 4 times i hit vtec in 2nd and when it hits 5200 rpm where i have vtec to engage the car just dies and check engine light comes on. Once the rpms drop till about 4500, the car will catch itself and go again.

And also this does not happen everytime. It randomly does it

Say i drive down the road 10 miles to walmart itll probably do it 4 times out of the 8 times i have to stop and go

I really need some help. Thankx guys

check your wiring, sounds like you have something loose, if all else fails, do a complete tuneup including fuel filter, plugs, wires, cap and rotor.
Check your grounds, especially the engine harness ground near the thermostat housing, if it's loose it'll shut down your fuel pump.

Alright thankx ill check the grounding.. I just did a complte tune not more than 4 months ago.. plugs, plug wires, oil, oil filter, rotor, cap everything bedies fuel filter..

Wouldnt a lose wire cause problems through all gears and all rps though?

I appreciate the response thankx

possibly, but another question, do you have any check engine light on?? I would start there first.

I just re-read your original post, Check the wiring to the vtec pressure switch, and check your oil pressure, if the ecu doesnt' see the right amount of oil pressure at 5200 rpm (vtec engagement) then the vtec will not kick and the car will fall flat on it's face and the check engine light will come on for vtec oil pressure. Check the pressure switch wiring, I bet its something to do with that, or you are just low on oil.
let me know

Also check your TPS my GSR did the exact same thing and it was one of the plug pins broken off of the TPS. Paid $25 for a new TPS with lifetime warranty off ebay, calibrated it and problem solved.

I do have a check engine light that comes on with the stock ecu in cause the 02 sensor is out.. but with the Hondata its not on but when the car dies the check engine light comes on..

Wheres the vtec pressure switch?

And thankx guys ill check all this tomorrow

vtec pressure switch is right by your distributor, closer to the front of the car, it's a 2 wire plug and I'm pretty sure it's green
