90 Eagle talon tsi fwd.
everything is stock except big16g

car will start up, idle reallly low and then die. will start right back up and will stay running if i give it gas. once the car warms up i have no problems at all. sometimes will take 10 minutes to finally fire up and is fine after that. had an obd1 scanner, heres what came up:

coolant temp sensor - replaced afterwards
knock sensor - deleted balance shafts i think i need a 2g knock sensor
crank angle sensor - is this the cam sensor? and will it randomly work when it wants to?
and then cylinder 1 random misfire- my cam to crank timing and ignition timing are perfect, coil pack is fine, plugs and wires are new, car doesnt act like its misfiring?

should i just go ahead and buy a cam sensor? seems like the only culprit?
