drivability issues
 

ok i got a weird issue... i got an ls/vtec in an ef civic... if i drive the car at partial throttle in any gear the engine will jerk like no other... if i switch the outter two wires on the tps sensor it will drive fine except on hard launches which is understandable as its reading the voltage incorrectly...

ive tried a new tps, a new throttlebody, ive checked and checked the voltage on the tps and its on point... any suggestions??????????

sounds like you have a incorrect wiring issue and need to be fixed or it could be in the tune have you had it tuned??

Sounds like you're trying to run an LS VTEC with an ECU that wasn't tuned for an LS VTEC. Oh, there's your problem.

Also check your MAP sensor.
