Explain please

Was changing the fuel filter etc. And kinda done something with the cable loom, in other words organised it. So everything was ok, even was happy that the fuel consumption decreased.

Then I was feeling this strange idle problems....400-1200 lol, wanted to adjust it....so I did....ofc forgot to disconnect the TPS. Well it didn't help so after a week I started messing with the engine again and I found out that I forgot to connect the TPS when I was messing with the loom LOL. I R ASHAMED of myself.

So, my question, how come the TPS wasn't connected and the drivability didn't change, same as w/ the TPS connected (except the idle). Guess it's all bolox to even have it connected LOL. Explain please :D
 
if i disconnect my TPS, my engine tops out at 3k rpm. weird that you didn't notice, unless your an eco driver that shifts up at 2500 rpm? :lol:
 
Ok Paul, so I take it as normal...but I wonder what purpose it has...if it's "almost" the same :confused::D

Oh and yea I shift at 2-2.5k RPM :D
 
maybe tps is used for economy and works with the maf to tell the ecu when the engine is under load??
 
yeah, also though that it only measures engine load. Would love to see my ga14de air/fuel ratio map.

But I also found out that I have a better fuel economy and though it was silly that a fuel filter can change it, mby tps?

but I guess there is no performance change w/ or w/o the tps connected.
 
The TPS only measures how much the throttle is open, so it can adjust fueling. I would imagine that it might run OK using the MAF, but it won't be perfect, just like it doesn't run quite right with no MAF or lambda.
