ok well what its doing is what your saying the hesitating on accelerating also it doesnt want to sit below 2000 rpm and I would really like to know because I am still in high school and even with my discount working at a parts store I don't really have a lot of money to be throwing around, when I pulled the 02's they looked fine other than a little bit of soot on them. also when testing the tps should I be checking the with the pigtail ungplugged or should i just do it with it in so I know it has power

 

well i was planning on changing the o2 sensors over the past weekend but i ended up having the water pump go bad on me, so when i was changing it my dad didnt like the way the wires were sitting because the covers were old and crumbling so he pulled them off and wanted to re tape them and come to find out the wires on the tps were bare and touching each other. seperated the wires and now it runs fine, thanks for the help.

 

I've been having the same problem for a while and its driven me crazy almost to the point of wanting to sell my 94z. I have a six speed and it bogs in the low rpms too. However, it only does it after ive driven for a while. But yeahthe engine studders and loses tons of power (especially when it's hot out). I think its a temperature issue, so i bought a switch that turns my fans on at 185. I'll let you know once i get them installed.
