ok well ive been busting my head on why my car running on safe mode,it wont past 5500 rpm,i have no cels and im out of ideas,my car is a 95 civic with a jdm b18c spec R

 

Is this under a load, or in neutral?
What ECU are you running?
Does it hit Vtec?

 

well the owner before said he was running a p72 on it just fine shifting normal hitting vtec and all when i bought it i took my p75 just to get it from his house to mine and the car was only going to 5500k i asked him and he said it happened to him and doesnt know why,so now i have it and its still hasnt past over 5500 and im running a chipped p75 vtec wont engage cause its program to kick in at 5600k and i cant past 5500

 

bad ecu? any cel's?

 

nope ecu working just fine and till yesterday no cel now i have vtec switch and thats not enough to cause that problem

 

Is the oil low?

Why do you have a VTEC switch...?

EDIT: I see what you mean now... VTEC switch CEL code. I thought you meant a manual VTEC engagement switch that some people like to install...

 

dont know oil is perfect

 

Fix the VTEC oil pressure switch problem before you go looking for other problems.

 

its a wire problem ima fix it tomrrow to late now

 

my brother has the same problem what wiring did you find wrong?

 

noooooo, he's saying the VTEC oil pressure switch code is a wiring problem. He hasn't figured out the cause yet for the overall problem of this thread. Just stay tuned for results.

 

well wires in the ecu harness are cut and rewired when i bought the car so i just followed the wire from the switch to the ecu and sure enough there was a cut,now my car still isnt passing 5500k and now it hesitates at 2k and on idle it goes crazy i think its the iacv but would it cause it to hesitate when getting to 2k

 

is your oil pressure switch on? check your cluster...

 

nope only two lights on on cel for iacv and srs

 

have you tried cleaning the iacv?

 

i was in the process i called my wife out to hold the iacv while i plugged the to hoses and it started raining she freaked threw it on floor an ran inside lol,now i got to get another one,but that wont cause it to red line at 5500

 

lol.. it must have been acid rain.. anyways that seem to be your only problem so far.. so it could just be that.. replace it and let us know what happens.. or at least clean it if its not damaged..

 

damn, i'm having almost the same problem right now with mine, but i have a b18b1 in mine and it wont go past 3500, i dont know what's going on

 

^^sir i feel your pain all these si's try me all day eveyday but i cant race them,soon you'll see,and yeah that will be the first thing tomorrow ill clean it tomorrow

 

Yeah my bud's comin over tomarow we're gonna clean off my IACV, FITV and then try and figure out what the **** is going on lol
