part not discovers (lacking engine power)

[Teyrar]

hey i just had a car in lacking engine power i ran all test with compression tool path test and test drive couldnt find part so i stripped entire engine down replaced all piston and rings as 3/8 was faulty and i read that some pistons might not show as faulty onf orum so for safety i replaced all

i replaced fuel pump filter oil filter air filter fuel rails spark plugs ignition coils still the part was not discovered or ticked i literally too the entire engine out of car and put it back piece by piece and never discovered this part

any idea?

i took every thing from car and placed back minus body work and drive wheels / suspension and it said lacking power not handling i figured air filter but i replaced filter and got nothing after rebuilding entire car

What about the Cam and Timing Belts?
Also the Throttle?
What Engine is it?

[SHTN]

What often can be an issue - clips on air filter. Or It may be a part that the car was lacking in the first place (and still does)

Are the housings bad, is the engine block too far gone. Did you repair the entire air filter not just replace the filter.
I've had a car fail because i never replaced the plastic base of a filter.

OP, you're contradicting yourself. In case of "car lacking power" issue, how did you manage to use test path and track? The game should've told you "can't start the engine".
Since you disassembled/assembled it completely, the undiscovered part may just be missing. And you mention railS and coilS, so it should be a modern V8. Is the throttle installed?

If that is the case, the undiscovered part must be something other than engine related (otherwise as said, you would not be able to take the car to the track or test path). Missing license plate or something?

[J.Random]

No, I'm pretty sure that if the broken/missing part is in the "car lacking power" category, OP should not have been able to use test path at all.

I could not start car when it arrived but I replaced all belts throttle starter and fuel rails and pistons rebuilt it all and it started but still did not uncover the part that was undiscovered in the lacking power catagory

I just replaced filter not clips or covers hmm maybe should have checked them

[Teyrar]

I sent it back unfinished as I could not find part but next time I'll check air filter box as I replaced every part in engine with under 80 percent and the mission was 75 percent repair it was a v8 4x4 forgot name but I lost internet due to snow so could not check replies and new did check clips or casing on bottom of air filter just the filter it self was replaced as I didn't thing casing would be under power category so I focused on engine more than anything.

Took me 1 hour 35 mins before I quit and sent it unfinished but hey I got achievement haha why was license plates mentioned ?

Could of been an exhaust somewhere..

[Hans Blitz]

You could check rod caps but thats usually falls under noise's from the engine bay.

When you do a compression test the caps will not show up, you have to remove the oil pan to examine the rod caps manually.

@ blackrain i replaced full engine
@ convey full exhast was over 80%

[BonPadre]

Could it be that this car had those small intercooler ? very easy to miss.

Now indeed, still very often it's the casing that needs some attention too.
I remember one where it also took me more than a few minutes to check all the other stuff aside from engine for that. and it was the filter base. In those black plastic ones, not as easy to spot as the old metallic ones fully rusted.

Just spent thousands of dollars and over an hour trying to fix a car up to see what the hell was wrong with it. AIR FILTER BASE. THE DAMN HOUSING TO AN AIR FILTER CAUSED LACKING IN POWER.

Lol, how Stupid is that! I know what you mean, Like if I do not Wax my Chrome Air Cleaner at least once it will cost me at least 100 Horse Power loss Lol.

On some vehicles a cracked air cleaner can cause a issue because the air flow sensor gets effected because it requiers a perfact seal. I do not know why it dose, but it dose. So as far as I am concern, it is just another new car thing to me.. Even tho this is a old article out of December 10, 2017.. Just saying..
