m35 stagea constantly going into limp mode

[Cyv]

Hey guys, first time posting here.

I've had my m35 stagea for about 6 months now (250t rs our) and i absolutely love this car. ever since about the start of last month it decided to enter limp mode on me. since than i have replaced a lot of parts. Started with plugs and coils and that fixed it for about a week, then i moved onto cleaning the intercooler piping and tb, same thing happened as it was fine for about a week then started going into limp mode again. then replaced the throttle body, maf and accel pedal position sensor and did all the relearn procedures. car ran good for almost 2 weeks! and well this morning on my way to my morning college class it wouldnt even leave my driveway without entering limp mode. I'm honestly at a loss with this car and not sure where to go next with it

Can anyone think of anything else to diagnose? i dont have a scanner of my own to check the dtc's when it enters limp mode but im working on getting one.

to clarify, my stagea is a 2001 with 124000km on it. always maintained properly in my ownership as well.

I had the same problem just recently, going into limp mode  with an nm35 2003 model but is was limping  once a week or 3 times a day .( 149,000k)

There was no perceived pattern.

The mechanic swapped two relays around . one relay was the lights and unfortunately  I can't recall what the other was . PM me if you haven't resolved the problem then  I will visit him Wednesday  for you, as I don't come onto the forum very often. Obviously the relays were interchangeable if that helps.

He mentioned that perhaps there was some moisture or a poor contact. sorry I can't be more useful

Previously when this happened  a few years back, a throttle body was replaced but you have done that already

Might sound silly, but check all of your earthing points (and maybe add a few).

The earthing points on M35's are really poor and can cause some odd characteristics.
