Still throwing p0102 & p0118 after changing parts + hesitation after washing engine P0102- Low MAF voltage. Checked continuity between pcm & changed MAF, still there after clearing codes.
P0118- High coolant temp output or something like that- Changed sender, did same things as above.
Hesitation is below ~2000 rpms and involves sputtering and loss of power. No codes for that. Just vibrates till it gets out of hesitation mode, sometimes it's below 1500, sometimes not. Really random. Happened after I washed the engine bay I think.
HELP PLEASE!!!
THANKS!

I'm not an expert but that happened when my girl washed her engine in her stang gt. It eventually went away. I wash my engine quite frequently and its never happened. I just try to stay atleast 2ft away from almost everything. and I don't put a lot of water pressure around things that look sensitive like the intake and wires and the computer. You should be fine. UNLESS you stuck the hose right up to your intake and held it there.
I doubt you did that though.

It's an LS1 in my RX-7, so I have none of those fuses, just a modified harness. I think we put a resistor for something that has to do with shifting when we did my harness too. How long does it take for gas to go bad btw? My gas is ~30 days old I think...

your gas should be good I'd think gas would go bad in much longer than that I'm taking a lucky guess at about 3 or 4 months. Just chill and make it do what it do till you put gas in it again. It should be okay but if it gets worse get it checked out.

It's a pretty simple circuit. You either have an open between the ECT sensor terminal A and the PCM or terminal B and the PCM. Either condition will cause terminal 74 on the blue PCM connector to only read the +5V pull up voltage. Without the correct ECT data going to the PCM, you may never enter closed loop operation.

And don't forget to check the sensor ground circuits by doing a voltage drop test. Make sure that the sensor ground is less than 50 mV with ignition ON. Less than 20 mV is ideal, but in the real world less than 50 mV is acceptable. If the ECT ground is higher than this, back-probe the sensor ground pins from the ecm to ground. This may be the cause as well. Good luck.
