pauly_adams Posted August 27, 2012 Posted August 27, 2012 hey all, my 280zx is having some issues with hesitation from 2000rpm upwards i is very lumpy, it is like its hitting a rev limiter, i checked all connectors etc there all fine although i found that when i disconnect my tps (throttle possition sensor) it runs fine but is realy lacking power. i swaped over the tps and still no luck, i adjusted them to spec and still no go. does anyone have any idea what would be causing this as its driving me mad. cheers pauly Quote
pauly_adams Posted August 27, 2012 Author Posted August 27, 2012 i forgot to mention that at wide open throttle it is fine has plenty of power and doesnt miss when the tps is connected but is lacking power when it is not connected as i thought it would Quote

pauly_adams Posted August 28, 2012 Author Posted August 28, 2012 i was just the tps, it must have had some moisture in it, i just sprayed some wd40 in there, blew out with air cleaned terminals re set and its now fine i might start making up a efi trouble shoot due to so many issues ive had. there finaly all fixed the last was a fuel pressure reg Quote
