Problem! All opinions will be appreciated.
2002 S2K vortech supercharged with intercooler. 47000 miles
I shut it off it was running great - the next time I started up I have no power below 3000 RPM.
The codes are reading misfire 1,2,3,&4 obviously. I have to get the RPMs above 3000 and ride the clutch to get going.
On the freeway it seems to be fine except the air fuel/ratio gauge is going nuts.
Have had four people look for vacuum leaks. Sprayed Carb cleaner all around Idle never changed. Disconnected the catalytic converter, no change.
disconnected the air cleaner box, no change. disconnected the intercooler from the intake, no change -sprayed carb cleaner in the intake rpm's actually dropped.
Checked the fuel pressure no problem.
Now I'm thinking the map sensor. before I take it to the Honda dealer.
I would appreciate all your thoughts.
Thanks a lot.this website has the smartest S2K people in the world. HELP

 

Do not take it to a dealer, most of their techs wont be familiar with the s2000, let alone a super charged one. Find a reputable tuner shop. What engine management at you running? Larger injectors and fuel pump? Have you checked your spark plugs?

 

Need more info.

Aftermarket injectors??

Can you get your hands on a fuel pressure gauge and tap the fuel rail?

Aftermarket fuel pump?

Oem Plugs?

How much boost?

 

What are the exact misfire codes?

 

Okay folks,,, right now, I need all the help I can get. Itook my car to the "Datsun Doctor" in Waterford Hills, Michigan. (6/26-7/17)I do not even think the guy looked at my car. I went there to pick it up lastnight. We had bad storms here w/hail. My car is a garage queen,I had to get herhome before the storm. I was pissed he even left it outside.


To answer your very kind replies/questions here we go.

@s2klariat - I tried to find a reputable tuner, here inMichigan. I asked my local foreign auto parts store and they gave me this dumbshit.

@wisdom - I don't have the exact codes.

@iDomN8U

I bought the car, last year from a wonderful guy inConnecticut named Mark I neglected to ever ask those most important questions,.I emailed him and his email back.

fuel pump was upgraded to match the supercharger

My local garage/friend took off the fuel regulator the idol did notchange & said the fuel pressure was good.

I believe I am running six PSI of boost.

All opinions appreciated
