i wante to know can i use an n/a tps on my 7mgte because i think mine is shot. my problem is i just put the head back together after putting new plugs and valve cover gasket and readjusting the tps and know it idles real rough and i cant rev past 1800. before i even did this it wouldnt idle on its own till it warms up i just had to hold on the gas till it started to warm but i could rev to what ever. any help would be appreciated.
