Hi,
I have a slightly modified 2017 TCE 90. It's been a company car until I bought it so it's clocked now at almost 200k km (~120k miles).
Since autumn last year, it started reving up to 2000 on start and keeping it there for about half a minute before it comes down to 900. It's automatic, and if I try driving before it is done with this little tantrum, it uses the clutch to not let me go above ~10mph.
I tried cleaning the MAF, then found it has a MAP, not a MAF. Tried looking at the IACV, seems it doesn't have one (uses the throttle alone for idle). Cleaned the turbo pressure sensor. Cleaned the throttle body, but the issue is still there.
-I thought it was temperature related, though it does it even when it's warm outside.
-Usually does not do this if it was already running in the previous few hours.
-Sometimes it revs to 1600 for 10 seconds and is ready to go. Other times it goes to 2000 and holds it there for 30 seconds with little rhytmic blips every 2 seconds.
The exhaust was modded, the cat was modded, K&N filter and it's been remapped. It's significantly louder than before and when it starts revving up on start I am just waiting for my neighbours to come punch me (I know I would)... I know it's not good practice, but due to cringe, when it starts doing this, I sometimes just turn the ignition off and retry after 10 seconds. Sometimes that works.
I hope the mods are not the cause as this was not an issue when they were done but about a year after the last mod.
Anyone had a similar issue? Any ideas what could the cause be?
Thanks
