hi guys, After solve the problem in cylinder one cause a blow AEM FPR. Now I'm having troubles when press the gas, the car bogs and die. Timing is on spot whit light.

Idle all day perfect, When in gear and try to take off it chokes and hesitate.

LS VTEC
81mm darton sleeves
B16 head p&p 3 angle, spring retainers and stock valves
SRP 9.0:1 Eagle rods (195-200 compression)

When press the gas the wideband goes completely to lean (18 AFR and blank) sputter and chokes.


Any help will be appreciate.
Thanks

 

Check ur tps

 

Vac leak possibly

 

^ This is my main suspect but I already bath the intake and hoses with carb cleaner and not find it. Need to check further under the intake.

 

A vac leak should cause it to idle really high.
Make sure you don't have your TPS and MAP connectors reversed.
How is this tuned? Have you tried adding fuel?

 

yes, I drain the tank and add new 93 and fresh methanol.

100% not MAP and TPS switched this start suddenly.

It is in the same tune since 2012 working flawless, like said above this start suddenly to the point the car is now not drivable.

Just in case I put new TPS and Test another MAP and the same. No CODE.

 

Update, double checking all, measure the TPS .48v closed and when I go to D11 at the ECU found .40v. It's normal all that loose from sensor to ECU?

I'm thinking in throw a cable from d11 to the TPS directly.

 

the internet cannot fix your problem, take it to a shop to diagnose it.. something else is broken/wrong

 

Continuity Trace the TPS wires back to the ECU.
You can also use your EMS datalog to show you which inputs are reading what voltages.
Sounds like you are on the right track.

 

After 2 months, Find a new ex harness and installed it with the new ECU and stock injectors, map and a TD-87 from a running R engine.

The car still do the same, old ECU, Dizzy, TPS and MAP works perfect in my friend engine.

The only mayor change I perform was a B17a exhaust cam, when the problem begin, cause the lobes have excessive wear but this not change nothing, the problem still the same.

Any advice will be appreciated!!!
