This car has been a problem from day one damn near replaced everything on the car already but yet it still wants to screw up so gotta keep fixing it

Anyway its been throwing 23 for awhile the sensor can unhooked when we yanked the motor for a clutch job but now its driving like crap itlll sit there and bog then take off sometimes it just started throwing code 7 recently and I already replaced and calibrated the Tps earlier this year and I just rechecked it still in specs and hooked the knock sensor back up a few days ago them the light came right back the next day. It would also get stuck reviving at 3000 rpm any ideas or imput would be appreciated this car has been a huge pita

Thanks

 

Search idle problems. You need to take off the sensor on your intake manifold, clean it and screw the plastic screw in and out 1/4 turn. There is a whole subject on this problem. It shows pictures and everything. If you have any questions pm me. Mine was doing the same thing. I didn't think he was related, bit sure enough it fixed it.
