Hi guys.. just yesterday, my car started acting weird. When i step on the gas.. the RPM goes up normally, but i feel a lot of power loss starting from 1800 RPM and up. As i floor it, the RPM rises, but no power like before. I see the RPM dropping slightly and it goes up as i hold the gas. This happens on every gear, but i can max out the RPM and also cruise at high speeds. It's just that there is no power, it feels like a civic. any ideas? I did tune up some time ago, and connections are all tight.

 

sounds like the auto slipping check your fluid

 

If slipping and fluid level ok, check charge voltage at batt, TCU.

clogged cat, maybe?
clogged Air filter?
Clogged fuel filter?
something is most likely clogged

 

Ok.. something might be clogged i also believe so... OH and it doesn't do this when the TEMP is cold. And even when the engine WARMS UP, this problem occurs ON and OFF, but most of the time, it is losing power.

 

Coolant temp sensor? Maf? Ign coils? Vaccum leak?

 

While cold, O2 is sleepin. TPS gives ECU the basis for guesswork.

After warmup, TPS is not used - except for A/T. Warmed O2 gives accurate readings, that is now by used ECU.

--->Could also be O2? U have to swap blindly or get a reading on mentioned sensors when problem is acute.

The "it feels like a civic" -fault description is quite vague, could mean the smell, engine power loss, slippin tranny, squirrels munching wires...

 

This sounds like the tranny is slipping....If your rpm is going up but your speed is not correspondingly with your rpm then i would say the transmission is going south....
