I had a intake gasket blowout on cylinder 1 that I apparently had been there a while, so I decided to do all of the usual maintenance while I had the intake manifold off. Clean Throttle body, clean IAC, replace vacuum lines, new PCV, plus, and new FPR. New gaskets for IM and TB. I did remove the fuel rail as well. I did take off the Throttle Position Sensor to clean the throttle body well and I took photos and marked where the position was.

I got it all back together, fired right up but idled at about 2000rpm. Later it started surging every 2 seconds or so and stayed like that. I rechecked as much as a could but I cannot figure out what is going on. I unplugged the TPS and it ran like crap so it is working I suppose. I might have a small vacuum leak at cylinder three fuel injector maybe. What should I do next? I appreciate your help.
