My VE/B14 has went from heaven to hell, i have alot of problems

Mr_VVL · 06-08-2004, 04:47 AM

Well my swapped worked fine for a lil while, with mods such as, Jwt comp,sr16 cams, s-afc (maf not hooked up just throttle and rev) then one day i turn it on and it it is at 1500 regular when warming up then it goes to 500rpm bout to turn off, then i turn it off and turn it back on and it revs to 1500 then it goes back down and turns off, then i fight it to stay on on the other try and the <A TITLE="Click for more information about car" STYLE="text-decoration: none; border-bottom: medium solid green;" HREF="http://search.targetwords.com/u.search?x=5977|1||||cars|AA1VDw">car</A> runs like sh*t, and my S-AFC is not consitently reading 100% throttle at 5.12 volts, i get mad..

So i check my afc connections and it still reads 100% 5.12 volts, disconect battery and then i hope it goes away, and it dose not.

i check all wires on tps and they all give me a 5.12 volt reading at all times.i think the tps took a sh*t.

Then i drive the car and most of the times i hit 8grand no problem, but sometimes it hesitates and i get fuel cut after 7 grand. (prob tps)

Now when i drive it and i downshift it is running completly too rich, instead of the old smooth VRRRRRRRRRRMMMMM while revs going back down its more liek VRRRRR VRRRRRROOOM VRRRROOOOM VRRRROOOOOM it dose not keep a solid sound it just keeps breaking up and throwing some quiet backfires u know like no solid downshift anymore the sound is all broken up.

on top of it the car seems like it has gotten a bit slower, also i found out some hose from my charcoal canister was not pluged into intake for vaccume and i made a custom hole on my ve black intake thing so it can go back into intake as it did stock,

the car/motor is giving me some crazy probs, please help

my boy said he got a tps for a de thats a 96 will this work? prob not, can anyone trade me, thanks guys

it is 4 am so i might add some in tomorrow lol

KNOCK SENSOR

98SE(-R) · 06-09-2004, 02:23 PM

vaccum leak? or lack of vac lines? that's the #2 thing to check when your car has a rough idle and misfires. first thing to check is plugs.

i dunno, just trying to help.

sr20sleeper · 06-09-2004, 02:41 PM

Did you check the ECU for codes? Could be the knock sensor like the guy said, i was getting a knock sensor error and i had similar problems. The thing will retard your timing if it gets the wrong signal from the sensor right?

0403 Throttle position sensor The TPS circuit is open or shorted
0205 IACV/AAC valve Check the IACV/AAC valve & circuit.
1005 EGR solenoid valve circuit EGR valve & EVAP canister purge control solenoid valve is open or shorted

Guys i need a tps please help!

22620-31u01 TPS Sensor
I found a part number for SR20VE N1 motor.
you can try to cross reference it w/ the part number for the lowport TPS.
Im pretty sure it should work, thats all i could find for now.

You can use the same TPS that comes on the 5 speed B15 SR20DE cars and the newer G20s from 1999 and up

To get rid of the EGR Selenoid light get a EGR selenoid an plug it back into the harness and tape it onto the harness. The computer just needs to know it is there.
