ok so here's the skinny... a while ago i blew the old D16Z6 and i had to swap in a D15B 3-stage VTEC.. cost me alot and the mechanic gave the car back with the check engine light on.. he told me to hold onto it cuz he needed room in his place to work on other cars and the car could "run" anyway.. Well i finally took it back and he's puzzled by the car because he cant seem to figure out what's wrong with it.. the computer says its the MOP/BRO sensor (a friend told me thats the MAP/Barometric Pressure sensor).. any ideas?

I've been having a problem of going past 80 MPH the computer will limit it and wont let the engine rev past 5,500 rpms on 3rd (ATX) and sometimes while driving it wont go past 5,500 rpms on any gear.. any ideas? please help cuz this is urgent and any help is appreciated! thanks!

bump!

the mechanic had put the Y8 manifold when he did the swap and kept the MAP sensor on there.. when we took it back, he got the MOP/BRO code and got the D15B IM and took the MAP sensor from there and dropped it into the Y8 Manny.. it worked for a few minutes and then started throwing the same code again..

oh and the distributor was leakin oil out from under it and stopped working about two days ago.. left me stranded on the road and had to push it home (about 10 ft hehe) but w/e aside from that i cant figure out what's goin on

its the Y8 ECU from what i was told the system is OBD2. it runs fine with that ECU the only problem is the vtec kicking in on time (cuz when i got it back after the swap it would engage 500 rpms late i.e. 6,500 rpms) so i was thinkin of replacing the single vtec solenoid that came off the Z6 and put in the dual vtec solenoid and wire the red wire to 12V source so that 2nd stage will always be engaged.. what do you think? there's just so much [email protected] goin on.. like i cant go past 80 mph for some reason and sometimes the rev limiter cuts in at 5,500 rpms for no reason..

i just pulled the distributor today to return it to Advanced Auto Parts and replace it.. after that i'ma clean up the engine before i put it on and then i'ma swap the VTEC solenoid and wire up the red wire switch to be on all the time and have the green wire switch hook on with the ECU

sorry i didnt quite understand that.. could you rephrase that? oh and to the rest, i pulled the Distributor and found 2 sensors and the tranny case covered in oil. my cousin whose a mechanic told me that its possible they coulda shorted out..

well getting back to the main topic (after seein my thread gettin jacked lol) Speedjunky, the green wire is for second stage activation and yeah i'm wiring in it up that way to see what happens. i dont think its the MAP sensor because 2 MAP sensors cant coincide in breaking like that.. my cousin whose a mechanic told me that its possible, however unlikely, that the oil which spilled over the tranny case could have shorted out two sensors that were directly under the distributor. They are both mucked up with oil and stuff..

For anybody thats watchin/readin this post i thot i'd let yall know we just put in the new distributor and new transparent cap and rotor.. replaced the Z6 vtec solenoid with the dual vtec solenoid.. car barely starts and i'm guess its due to the first stage vtec that causes it to run rich and therefore struggles to spark up.. tomorrow i'm replacing the battery terminals and doin the wiring work for the solenoids.. wish me luck!
