i just did an obd2 gsr swap into my ek and it was running just fine for around 4 days. then when i started to hit vtec the whole car would jiggle back and forth and the speedo and tach would just go crazy. i'm not sure what could be causing it. i've already replaced the distributer and that doesnt seem to be the problem. i'm running an obd2 gsr ecu and i'm throwing the secondary o2 sensor, fuel pressure, ,and crank position sensor. plz help! thanks

 

bump! plz help me!

 

make sure oil level is full
then erase the codes and drive it to see what comes back and go from there

 

oil level is full and the same codes are showing up. i'm wondering if this is a fuel problem. because vtec still engages but it just pukes out but keeps going. its happeing in the lower rpm's also.

 

the correct ckp sensor reading is needed for vtec. check all the wires on and neer the ckp sensor
(bottom of lower timing cover)

put a fuel gauge on there to see the fuel pressure
u may have a bad pump
