Hi, I am new to this forum. :) I'm hoping someone can help me out with this. My gf blew a head gasket on her 98 sportage and I recently replaced it. (no shop manual :( ) Before I ripped it apart I brought it up to tdc to check where the timing marks are.
Here is my issue check engine light is on. I put my scan tool on and I am getting these codes: 302;171;1624 and a 1115. the car is a little hard to start and it has a mild rough idle to it. I put new plugs in and 2 new coil packs.
Thank you

P0302 Misfire detected - Cyls. 1-4.
P0171 System too Lean - Bank 1.
P1624 MIL Request Signal from TCM to ECM.
P1115 Engine Coolant Temperature Signal from ECM to TCM.

as for the p302 reset the ecu to erase that code after you changed plugs wires coils. i noticed you didnt replace wires that could be the fault.
as for the others the p0171 is probably due to the misfire.

the others have to do with the transmission control module. thats the best i can help.

see a mechanic you trust about the last 2 codes.
