ok i got that fixed now i gotta fix my code 15 lmao o boy engine swaps are fun the code 15 doesnt come on the cel isnt on but my computer paper clip diagnostics says theres a error 15 lol so who am i to argue
code 15 is the coolant temperature sensor reading low. might just need replacing, but check the connection first. this is the sensor on thermostat housing that computer reads, not the one in head that gauge reads.
ok new problem now the truck will not idle when cold but i hold the gas down for a few seconds it will then idle perfect any clue man? i just realized i have a very small leak on the front of my intake manifold as well lol dam it maybe this could cause it to die at cold idle?
