I installed supercharger last night and on the first run it was fine. the car took off like crazy. then the next time I start it , its starts right up and idled fine. I drove normal to gas station and started to notice some hesitation. I filled her up and then it would not alllow me to hit vtec. it has gotten progressivly worse and now every time i give her more that slight throttle she starts to choke . It almost like it hits an RPM wall. It just starts to die and I have no power. This was a brand new fuel pressure regulator and was crushed accordingly. I even replaced spark plugs again and no dice. when I pulled to Densos out this morning, the outer rim was black, so I now I am getting enough fuel! PLEASE HELP!!!

 

Just to try and help you out some. Not sure if it will.

Are you using 1 step colder plugs?
Did you try to add 2 cans of octane booster?

 

yes, I tried using octane booster and did not work. I just got off the phone with comptech and they are sending me new plugs and a new acm! well see tomorrow what happens!

 

Hope it works out for you bro. You've been having bad engine problems lately. Keep us posted on the situation.

 

yeah man doesnt look like luck has been on your side, I hope you get all this figured out.

 

hope everything works out for you. Btw, when you get it all fixed, let me know so i can go up and take a ride

 

Well last night, I changed out my plugs and now I am not hiting the 3k rpm wall. it happens around 5 in 1st 4k in 2nd and up!! I am going to go to acura and have them check it out I think. I was having a similar problem about 2 months ago and it went away!
I have no clue whats going on!

 

Im going to forward this to my mechanic buddy at my dealer, maybe I could get some answers for you...... not sure how much experience they have with the S/C but its worth a shot...

 

Thanks.

I am thinking in the range of a bad coil or fowled spark plugs. I dunno how the plugs could be fowled already but you never now! thanks in advance!

 

I us noticed one other thing. this hesitation and problem gets much worse the longer I drive the car. If I drive it and it heats up it starts to get worse!

 

you should PM the other F/I guys, they may have some good input as well.

 

I have narrowed it down to be either a leak in the EGR valve gasket or a problem with my fuel system. I am not sure. it goes into acura next monday and well see what happens.

 

i was gonna say didn't you have this same problem b4 the S/C? last time sounded like Sunoco was the culprit. acura also said it was bad gas right? heat related eh?.....faulty computer? any CEL? good luck.

 

no CEL which is the weird part. I find it hard to beleive the car will run this badly and have no CEL! ITs almost not drivable at some points

 

wow no CEL..what's ur MPG now. are u still driving the car? i'd like to take a look if it's in Morristown. i'll race ya....;-) lol

 

Yeah I am driving it. My MPG has not changed really. The plugs look normal as far as rich or lean. I have no clue whats going on!

 

it's like ur computer is cutting fuel. is the "choke" rpm consistent right b4 Vtec? does it only happen when you WOT? can you slip thru to the higer rpm if you accel. gently?

 

its like a choke in the beginning but when I drive for about 5 minutes I cant go WOT without the car bogging down and wont let me clime any higher in the RPMS.

 

I can slip through RPMS is I hit throttle very gently!

 

it could be the drive-by-wire sensor. can you rev it up freely from the engine bay?

 

Just curious.. you did remove the thermoblock spacers right?

 

do you mean just sitting idle, yes. i can rev it how ever high when not in gear!

 

yes, i removed the thermoblock spacer!~

 

And you removed the UR Crank Pulley as well?

 

Yup!

 

that don't make any sense???


no load (not in gear) - you can rev no problem whatsoever.

can't be fuel system, can't it? you shouldn't be able to even rev up when parked if that's the case. what else monitor your speed/RPM/throttle position while providing fuel? ECU is the only think i can think of...if not one particular sensor. however any sensor failures/absence should trigger CEL and you have none (CEL).

it's not the rev limiter cuz you can slip to higer rpm.
it's not the pedal position sensor since you rev-ed it up at idle. it's got to be the ECU right?

is it fuel pump not providing enough fuel when the load is present? i've had a half broken (weak) FP creating similar situation when it's hot.

just trying to help. i don't think you want to deal with ecu or FP yourself anyway. just guessing. not saying for sure.

 

I am going to bring it to the dealer and let them sort it out. they have the computer reader to see what going on in the computer when engine is on!

 

I would think that even if I was running lean, THat I would get a CEL, NO?

 

yeah. it's prob. best at this point. doesn't seem like something ez DIY. let us know. good luck.

 

when i had the fuel problem, i got not CEL.. and i was super lean..

 

Well i went to the dealer yesterday to visit my friend. he was able to find a vaccum leak which had nothing to do with my install. the new gasket that I put on the intake manifold cover was leaking. I tightened it down and it has gotten sig. better. I ordered a new gasket and we will see if that corrects the problem!

 

Good Luck. Hopefully you won't have any more problems.

 

Well I will let you know later today when my new gasket comes it! but I can tell you that this is definately the problem.

 

Still odd that it didn't throw any codes, makes you wonder how the comptech acm is "tricking" the ecu...

 

Car is at my local dealer today. I was getting misfires upon startup now.

 

Any update on the diagnosis?

 

Acura has no clue as to what is going on with the car.

 

^ I am not surprised at all my friend. Acura dealership usually don't have guys who are familiar with Superchargers. However, we have a guy here named "John" that's been dealing with S/C for awhile. Call Sussman Acura and look for the Tech "john". Also pm Ryan to any further problems. I'll be you Ryan knows more about your problem than any of those Acura techs.

 

They have pretty much narrowed it down to have nothing to do with the S/C or the install. The seem to think that it is definately my fuel system. The tech thinks that I have a weak fuel pump. He said that the problem that occured before was most likely this and it didnt really surface until I needed the extra pressure from it. now it has pretty much bit the dust they beleive. I am waiting to hear from them today! they said that if it had to do with S/c it would not be happening at idle!

 

^ doesn't the S/C call for a better fuel pump? In other words, it's a different fuel pump....................................
