Hello,The car is a 92' Galant with a 4g63 DOHC. It had a hard cold start so I went ahead and ordered an NTK Coolant Temperature Sensor (as was suggested to me in a previous thread) from RockAuto thinking that was the problem, today I replaced...

No sure what an EPROM ECU is, but considering that this is a plain Galant without any mods, I would asssume that it has a regular ECU. I saw the ECM Tuning site but I'm not from the US so it would be well outside my budget to send it to them...

Ok, checked my diagnostic process and I was checking the wrong wires, turns out those are fine and there is continuity from both ends of the IAC motor harness, so I don't have any reason to suspect that anymore. Based on this I started checking...

Im not sure if its a useful tip, but on my automatic 2g that was having idle problems, the only way I was able to verify the idle air control motor was working was to leave the old idle air motor installed on the car, unplug its harness, and...

I tried doing this at one point and saw no movement with either of the AIC valves, the new one should be working so there is a problem in the harness or ECU, I'm leaning towards harness first because the inspection seems to indicate a faulty...

Hello, I posted a few days ago about a reliable brand for an engine coolant temperature sensor and received a lot of help, so I'm back with more problems that I hope you can help me with.The vehicle is a 92' Galant with a 6-bolt 4g63 and an...

It seems that most of you agree that NTK is the way to go to keep this affordable, so I´ll go with that one and call it a day. Thanks a lot for your responses, will probably keep posting here about the dozens of issues that the car has.

While I am all for supporting the supporting vendors, not everything has to be an OEM piece if you're not doing a factory original build, especially when the item is at a weirdly high price. We're talking $64 vs under $14, and this particular...

Store bought ive used since 94 never got a oem one execpt when i came with the eclipse i got from the dealership.

Last year I bought an NTK EF0099 sensor from Rock Auto for $10. I've verified that it is accurate, within probably 3 degrees F, at low temps like 51 degrees F. It seems accurate at higher temps too, like in the range where the 180 degree...

Surprisingly my Autozone temp sensor which I bought about a dozen years ago is still working.

Here’s a link to an oem sensor from a supporting vendor.https://jnztuning.com/product/oem-coolant-temp-sensor-ecu-1g-dsm-gvr4/

Out of those, I'd first go NTK Then SMP (I think I have a CTS from Standard in my parts cache) ...and then whatever else I could find if I was that much in need

Thanks a lot! I guess I'll look at those for replacement.

Hello, first post here so please let me know if I'm breaking any rules.I have a 92' Galant with a 6-bolt 4g63 and an automatic transmission. About a year ago I changed the Engine Coolant Temperature Sensor (shown in the pictures, 2 terminals...
