Went out in the car tonight let it warm u and realised the car is only hitting half boot rang a mate as i was a bit worried... but then tried again and hitting fine now at 11psi.

The Car is 93' wrx import only got induction kit and hks back box (only had it 2 weeks) ive ran a fault code on it and came up throttle sensor which i have but got to change over. would the throttle sensor do that i.e put the car in safe mode?

 

think if ecu sensers a fault it would go into limp mode, i was going a bit quick other evening and it had a slight miss fire and went to 9 psi for a bit so pulled over cheaked for codes but non,stared back up and ok back up to 16psi again.has done it b4 but drives out of it on m may stange!

but sounds like your thottle sensor may be intermitent so will be ok then not ok and go into limp mode???

 

no it never goes into limp mode just cuts out now and again when i drop clutch coming up to lights.

 

MAF?
