Recently I noticed that around the 2000-2500 rpm range that it bogs a bit or if you will, feels a bit sluggish. Thought it was my spark plugs, so I changed it. Didn’t solve my problem. Also when I keep the gas steady around 2000-2500 rpm, it idles a bit up and down like I’m on a 2 step or something. It runs fine, it’s just hat problem. And also it would randomly tick once every now and then. What do you guys think?
I mean tick around the 2000-2500 rpm once in a while
What do you mean it ‘ticks’?
When is the last time you changed the fuel filter? How are there cap and rotor?
It makes a ping sort of noise. I have yet to check the fuel filter and the cap.
yeah I had the same issue on my ls and type r swap, it’s pretty common.
and it’s a big mystery yet to be solved.
you might find some threads on it of you look up power loss.
I could never pin point it, I replaced all major components during my swap and I still had that issue.
I’ll post a list of things I changed.
engine
harness
ecu
all engine sensors
injectors
fuel filter
distributor and internals
ignition wires
throttle cable and bracket to p73
calibrated throttle p/s 3x
the main relay, did help the engine run smoother.
checked the mechanical timing. I did have a aem crank pully so it didn’t have marks for timing. I had to set the timing by setting piston #1 up and the cam gears set on marks.
only thing I never changed and was last on my list was the fuel pump.
might want to look into changing it out.
Well that might be an issue. But I have everything set to oem spec. Especially the fuel pressure regulator to oem spec. Was running super quick,
you did say you hear it ping, make sure your knock sensor is hooked up.
I had to wire the knock sensor to the.ecu right after the.swap.
For some odd reason, my problems went away. I just had the motor rebuilt. I guess the person who changed my oil added synthetic blend oil instead of conventional. The people that did my swap said it was recommended that i use 5-30 conventional oil. Runs better than when i first got the swap. Thanks for your help G2IC members!
