had a very similar issue on mine a few months back, my one turned out to be the mini loom on the crank sensor. Even when stationary it would kill the revs around 2500 and cause a misfire, i had someone hold the revs while i wiggled wires. Wiggling the crank sensor loom solved it, fitted new sensor and hasn't played up since.



I know you've fitted a new sensor but it could be degraded wires in the part of the loom that connects to the sensor, they get very hot down there due to proximity of exhaust and rad fans blowing on them...worth a looksy

 

03tibe85 IAT is in the intake piping, befor the TB. It is connected to the SMT8 and the temp readings are ok.



rob40 Thank you for the tip Will check it today, but when I fitted the new sensor I tried that whit the car ideling. Will do it your way



I knew that today the car will act up again... hot day so there was a ot of bogging and sh*t !!! Most of the bogging is at around 2500rpm.



I'm sure that with your help I will solve this f*cking problem. Thank you all for your time

 

At this point I would have just disconnect the TPS, run it for a while and se what happens and continue to do that with each sensor lol

 

Hah desperate times call for desperate measures

 

That car is asking for a full programmable, I hear Haltech Elite...

 

My mom told me not to play with boys like you :biggrin:

 

I have had Haltech, SDS, Microtech, also worked on Fuel Tech, Mega Squirt, AEM, and Mitsubishi and Subaru Reflash. I prefer Haltech by far...

 

Maybe one day, but for now SMT8 with dual rail setup. If it's not working as I would like it to, I will sell it and buy a standalone

 

Did you check what Intake Temp your ECU is seeing? Like I said if you tapped the SMT8 into the IAT then it could mess with the temp readings. Only way to know if the sensor is ok is to following repair manual testing of various temp vs resistance values.

 

Yes, the sensor is ok.



Today was again a very hot day. Decided to drive the car so I can monitor how it acts. The bogging is happening not only at 2500rpms. The problem area is 1800-3000rpms. Not a single bog at hight rpms. Very rare problems at idle. Press the gas pedal and instead of reving, the revs drop and it almost die.



Was thinking a lot about this f*cking problem and thought that I might have vacuum leak that I did not see before. Double checked all hoses, tightened the IM nuts and went for a drive... same sh*t.



Will disconnect the TPS and go for a ride later tonight!



One thing is for sure the problem is A LOT worse when is hot.
