Trying now to narrow down P0202 misfire, and what out of the 5 or so things one that cylinder can be causing it. I have changed the spark plug and the car is "Skipping" or running badly still upon starting(just sitting still). What little I can see the wire plug to the ignition coil looks fine and the heat shrink looks fine. Can tell what's happening deeper in the harness.
So, I swapped out the old ignition coil I had in another cylinder, bc I didn't really think it was bad. And I don't know if I had all the 3 codes I'm showing now that I found after borrowing an OBD2 tester from Auto Zone. I got the P0202 just from the dash. Now I have P2305(Ignition Coil 2 Secondary Circuit-Insufficient Ionization and P0113(Intake Air temp Sensor Circuit High). Maybe the dash only shows 1 at a time.
I swapped the ignition coils back out and still have the P2305. Not sure if I just need to erase that one and see if it comes back or not. Probably try that.
I also have tested the IAT w/multi-meter. So 1st question: W/it on 200K on OHMs setting, I get 11.6 and 11.8 when swapping around the leads btwn the 2 prongs more towards the top of the prongs. First I had one towards the base of 1 of the prongs to help it stay in place(bc I don't have alligator clips) and 1 at top of the other prong on 2 dif. Days(inside the house), they read 8 to 9.5. Are these too high, and does that mean the sensor is bad in some way? It does go down on the reading as it should when some heat is added near.
2. When I was told that the P0202 was general misfire, that's why I changed the sparky and swapped the coil, but if it is really a Fuel injector problem for real as the specific code says(circuit open), do you think Seaform cleaner is could be tried to see if it helps or don't bother?
And can the 202 be making the 113 show up?
Here are the details the OBD2 shows on the details about the P0202:
Fuel Sys 1 and 2-OL
All the STFTand LTFT B1's and 2's-0%
Veh Speed 0mph of course
Spark Adv-16.0 degrees
Run Time -4sec
have the same problem?
