I just went and changed the lower injector seals and o-rings and adjusted the tps via datalogger (10%). It was at 13% before. When I try to start the car now, it ussually starts on the second or third try. When it does start, it cold idles fine for about 2 seconds (3000rpms), then it drop to about 1500 and surges from 1000 to 1500 rpms, but in a manner that almost sounds like its really wanting to die. I have no CEL on. Anyone know what could have caused this? I didn't have this problem at all before I did the new lower seals.

do a boost leak test, they might not have seated in properly and now you have a boost/vacuum leak around one of them

yea, or one of the orings might have torn goin into the rail. it could be a half dozen things. pull em back out, inspect em, put it back together.

I kept trying to run it and eventually the Coolant Temperature Sensor CEL went on. I checked the temps in my pocketlogger and sure enough, they said 312 haha. I replaced the sensor and still got the CEL. So I'm assuming this is a wiring problem. I hate my car. Any tips with the wiring?
