Thanks for the suggestions.. Tps has been changed out following the TAB with a new sensor and rewiring the grounds but this was done 3 years ago when the tps problem was rampant with the majority of nsrt4.. I will check it out again to see if this is the cause... And as for the filter suggestion, it could very well be it. As I havnt cleaned the filter for a while. Something simple that I will test out tomorrow.otherwise it looks like the dealer will be getting my hard earned moneys..
