Tps Idle

[RamR33]

hi, having a bit of a problem with my Tps idle.

ive set my idle to 1100 with the tps disconected and as soon as i connect it,it goes down to 750/800rpm and most of the time stalls when driving and dont no why.

aac has been cleaned and new sparkplugs and coils and not sure if its the voltage on tps which havnt tryed yet.

also have a greddy e manage but not sure if the idle can be adjusted from there.

ive provided a pic if anyone can help me out.

may i ask why you want the idle at 1100rpm? that is massively high. it should sit at around 750rpm and the ecu is probably over riding your setting because it's so high. as for the stalling when driving, does the car have an atmo bov? if yes, then that will most likely be the major cause of your problem. if not then i'd say that the settings on the emanage probably aren't the best and it could do with a bit of adjustment. that said, might be worth checking your o2 sensor with a multimeter. it might be on its way out and causing the issue.

its because i cant go anymore on the screw on the aac and when i connect the tps back it goes down to 700/800rpm but then stalls and kinda goes up and down between700/900 rpm.

i do have a bov but plum back one not atmo but is aftermarket.

only last thing to check is the o2 sensor as u suggested as im out of ideas.
