No time for the car these days. Working really hard, but it's good for the bank account :biggrin:



Been thinking how to setup the intercooler and piping.



I was driving the car around town with my laptop pluged in and I'm 100% sure that my problem is not because of the TPS. The TPS is reacting all the time even when my car goes quiet. Voltage change is very smooth, no bad spots or something...



I'm stuck with this f*ckin problem, but I will keep trying



Any ideas ?!

 

Did you check the MAF/MAP?

 

Yep, my MAP is ok. Reading all the time. 0.30 bar at idle and 1.01 bar at WOT.



Can't see anything bad with all sensors...

 

I would remove the piggy back just to remove it from the equation.

 

I'm sure it's not the piggy! Thanks to it I can see all the live data and I see all the outputs. Everything is ok 100%.



Could it be the fuel pump or anything fuel related? 99% sure the injectors are ok, cause with the bigger once it was the same thing. Also it's not a single cylinder issue.



Fuel filter? Fuel pump ?

 

Typically, fuel pump and fuel filter issues will not be intermittent. When your fuel pump goes out, youll know. Your car will not start or go. Fuel filter issues would show up as consistent drop in fuel pressure. Also, not intermittent.



Hmm.....sounds vaguely familiar to a problem I had once. Check the ignition switch! Mine was so intermittent, we checked it, it seemed ok, still had the problem. Ended up buying the $13 part and it solved my problem!

 

Will give it a try. What was this 13$ part ? Why giving it more gas cures the problem ?



02 sensor? It was reading 14.6-14.8 all the time when I drove it today.

 

That should not be, it should vary a lot. Specially in deceleration.

 

Will check the ignition switch today, but I'm sure it's not the problem, cause when I give more gas it cures the problem.

 

Is your idle control valve hooked up and working properly? If its sticky it could basically cause a vacuum leak.
