2000 GSR TURBO,CAR BLEW RINGLAND OUT,WE REPLACED WITH A OBD1 B18C AND WE SWITCHED EVERYTHING OVER CORRECTLY AND NOW IF U RAP THE THROTTLE IT WILL ALLMOST STALL AND THEN IT WILL REV UP FINE,BUT IF U EASE INTO THE THROTTLEIT WILL REV ALL THE WAY UP FINE.
EVERYTHING SEEMS TO BE HOOKED UP CORRECTLY,AND WE HAVENT DRIVEN YET.
CAR IS OBD2 AND THERE IS NO CE LIGHT ON, I THINK THERE SHOULD BE WITH A CAR THAT SMART.

ANY INPUT IS APPRECIATED, PLZ HELP

 

throttle position sensor, there are 2 plugs that reach around there, if you switch them, it does that, also check the vaccum lines and fuel pressure regulator

i had the same problem when i was changing my intake manifold, i think it is because it doesn't make the right air fuel ratio, because if you switch the plugs (i am not sure what the other one does, they are both near the throttle) it would almost lower the rpm's when hitting the gas!

make sure you have the vaccum lines and all that going to the right spots, do you have a fuel pressure gauge? what else have you done to test this??

 

This may sound stupid but the O2 sensor may be bad. The A/F is reading incorrectly unless you have your primary O2 before the cat (OBD1). If you converted OBD2 to OBD1 W/O Changing the placement of the O2 sensors your car will perform that way and may not show a CEL yet. Just a guess though.

 

THE CAR IS OBD2 AND WE DID CHECK PROPER CONNECTION OF THE TPS AND THE MAP SENSOR, THEY R GOOD,AND IT DOES SEEM TODROP THE RPM UNLESS U EASE THE THROTTLE,FUEL PRESSURE IS GOOD ANDA/F IS READING PROPERLY.
REVS FINE AFTER 1000 RPM

 

that really sounds exactly like the problem i had, try to swtich the two plugs and just see what happens, and caps lock is not neccessary

 

I DID SWAP THEM AND STII SAME RESULT, I HAVE A FACTORY MANUAL, SO ALL IS RIGHT, I AM GOING 2 CHECK ALL VACUUM 2NIGHT,THE CAR BLEW ALOT OF OIL WHEN IT BLEW UP AND IS ORIGINAL INTAKE MANI AND SENSORS, COULD THESE BE OIL FOULED OR SOMETHING LIKE IT?NO CODES YET, BUT WE DID NOT DRIVE YET.

 

oil in the air lines could definately be a problem, i would consider getting new tubes, that can't be more than $5-10, this would be a good idea, also check your spark plugs... are they discolored? (rich/lean)

gas tank full? oil full? coolant full? oil filter good? fuel filter new? check everything twice, obvious (stupid) mistakes are sometimes the harderst to find

 

ANYBODY SEEN ANYTHING LIKE THIS?
PLZ HELP

 

VACCUM LINE 2 THE WASTEGATE BLEW OFF AND MOTOR SPIKED TO 20LBSWHICH CAUSED THE ORIGINAL BLOWN RINGLAND,REPLACED WITH JDM B18

THE FIX OF MY ORIGINAL COMPLAINT WAS A BLOWN OUT MISSING LINK
I THOUGHT THEY COULD SEE THOSE KINDS OF BOOST PRESSURE

 

is your caps lock broken??? seems like you fixed your problem

 

why u gotta be a smart ***, keep useless comments to yourself, thanks
