Couple day now my engine (B18c tuned with a Hondata S300) went into limp mode. at least i think it is, It won't cross 3500 rpm (revving at idle or driving)
No check light, no codes.. no rough idle or anything it just wont rev past 35k it just goes up to 35k and dies down then bounces back up to 35k and dies back and so forth, and this is with the throttle at a steady position
Things I've checked/replaced so far; ECU is working properly (I checked it by unplugging a sensor to see if it throws a code "it did" ) not 100% sure if that means its working, can't seem to find any wires in the harness that's broken, replaced the O2 sensor, new spark plugs, new fuel filter, check the injectors all is functional, fuses look good (not sure if i missed any), FPR works...
Things i suspect but don't know how to check if they're faulty ; TPS, MAP sensor and Distributor
Has anyone ever experience this before?? I googled a lot of stuff and tried everything that I found and could possibly my issue. but nothing worked..
(A bit of history before this happened: I replaced my clutch a few weeks back and since then every morning at start up the car threw a code 21( Vtec solenoid ) but during the day the code didn't seem to come back when restarting the car (weird) when i finally got time to properly inspect the solenoid i noticed the engine temp sensor wire was almost broken off the plug so i replaced that and the vtec solenoid, the code still was there every morning though....
Then this limp mode issue started (car work fine the day before), so while trying to figure the limp mode issue I check the ECU and saw some poorly connect wires and i re-did the connections and since then no CEL for the Vtec solenoid but i'm still left with this limp mode problem that i can't seem to figure out
Can someone please help?!
