Done a b16a2 swap into an EJ9. Got a problem and unsure on what it might be so if anyone could help that would be great. Basically turn the car on it idles fine, however when I open the throttle the engine bog down and stalls? Its running on a p30 ECU. Am thinking about sending it to H-tune to get socketed and basemapped, could this solve the problem? Dont really wanna send it off if its not going to fix anything. Hope this makes sense and if anyone could help id really appreciate it! :)
 
Check that you haven't mixed up the tps plug with map sensor plug
 
Pretty sure I havent, just tried to swap them and they dont reach eachother?
 
how much has it been ran? and how long has the petrol sat in the tank etc could just be dirty fuel
 
Hasnt been running since the swap as it just stalls, so would of been sat still for about 3 months. Gonna look into getting new fuel filter. Anyone know wheres the best place to get one?
 
Managed to swap the plugs on the tps and map sensor. Also fitted a new map sensor and now it doesnt stall but now it idles like a sack of **** + can hear it misfiring
 
Swap them back again. Get a volt meter and measure voltage at TPS with ignition on and engine off. Make sure it's reading around .45volts with throttle closed. If not move TPS till it does read that.
 
Ive ordered new TPS, should be here tomorrow just incase thats not working. Will get the volt meter on it! thanks :)
