Hey, I have a 94 acura integra...
recently dropped out the motor and got a donor car...had a LS vtec in it. pistons were blown...and car had no title...so i stripped it for parts. I rebuilt the entire thing inside and out, rehoned the cylinder walls, ordered new pistons and new rods...etc...when i first started it, it was idling rough...fixed it...had a crapload of CEL's...But also fixed them all
Now i'm having an issue...Sometimes the car would Idle normally...Sometimes it would idle VERY low...
it randomly happens...driving low RPMs is normal and fine...sometimes when i hit 2,500xrpm...It surges straight to 4-5,000xrpm and goes back and forth...
The problem:
when i accelerate hard it just straight Stumbles...the car will bog down like crazy and sound like it's havin a seisure...but once it hits vtec...it runs normal and runs very strong...
I had a chipped ecu in it, chipped by dinan(P28) but i figured it was a bad ecu...so i swapped it with a spare ecu i have...a p28 also.Still has same problem...
What i've done to try to fix it:
checked the fuel systems, replaced injectors...
checked ignition coils, replaced it
checked spark plugs/wires...all replaced
distributor is new
valve clearance all checks out good.
I'm not sure what it is anymore...Really thinkin hard about just going back to regular LS...But i Know i don't want to...Help would be appreciated...
stuff in the motor...just incase anyone has an idea...
skunk2 stage 1 street camshafts
pr3 pistons
p72 rods
gsr crankshaft
skunk2 Intake manifold( Yes i checked all vaccum lines and harnesses they are all correct)
stock fuel rails and injectors
stock distributor w/ msd dizzy
10mm sparkplug wires
ACT Clutch (Forgot what type but it's the whole kit)
p28 ecu
