I wonder if it may be only a quiet spot. If you keep the engine at that speed, does the car keep driving? Find a level road and hold that engine speed. It could be a resonance that is relatively quiet compared to the rest of the noises the engine makes.

 

That's not the case. The car is not reacting to my inputs. It just goes quiet and after that misfires, bogs ... It's really f*cked up when you are in the middle of the road and the car is not moving



The work continues ...

 

If everything is back to stock then all your SMT8 maps should be zero'd out...right?



Did you get the SMT8 Bypass plugs with the unit?

 

Still sounds like TPS to me. If fluctuating the accelerator pedal fixes and brings the car back to life, I would start their. If it backfires, it's still getting fuel. Something is off with the timing and you say it gets fixed when you give it more pedal.



Try a third TPS sensor. Ive had two new sensors back to back be bad! Not common, but can happen. Also check the wiring from the tps back to the main harness. Be sure it's not pinched or has degraded at all.



If you have a MAF, you could start diagnosing that as well.

 

03tibe85 yep, everything is "0" as I wrote before. No bypass plugs.



tibbytib I was thinking the same thing ,but I checked the TPS with multimeter and no issues. I can check a lot of live data with the software from Perfect Power ( SMT8) and TPS is one of them. I was watching it like a hawk and everything seems fine.



I have MAP and I wanted to plug my laptop and go for a ride , but I have lot of work these days. Work during the day and I lot of beers during the night Tonigh I will go for a ride and will be watching the MAP readings... I'm pretty sure that the MAP is ok, but still ...



Boost meter coming tomorrow and will be searching for intercooler piping.



I hope I can fix this f*cking problem, cause I want to feel a little boost

 

It's getting strange as f*ck !!! Went for a ride tonight and not a single issue! ! Close to 1 hour drive in the city. Tomorrow will be a hot day and we will see ...

 

Did you reset your OEM ECU after you replaced the sensors? It could be it took a bit to relearn what a good sensor looks like?



Where is your SMT8 mounted? Those things don't really like to be in the hot engine bay so maybe its acting up when it gets super hot?

 

Yes, I did reset the ECU before 3 days. I doubt it needs 3 days to find out that the sensor is good ?!



My SMT8 is mounted right next to the ECU. You should be really stupid to mount it under the bonet



Double checked everything tonight. TPS is working fine, all maps are set to "0" , nothing wrong with RPM, O2 readings were 14.7-14.8...



Will see tomorrow how it goes

 

Gremlins?

 

I'll find them and kill'em all
