Re: ITB Conversion on sixteen valve 4AGE On my inventory bigport AW11 a leaking exhaust manifold gasket induced the O2 sensor to read lean and it pumped gasoline in the motor. Gas economic system plummeted till I sorted it out.

The engine's AFR appears normal at cruise, but abundant at idle, as well as the stinky odor can make feel sick if i remain in the garage for lengthier than ten mins.

These work quite independently of every other adjustment to your ITB and when opened, let a little degree of air to bypass the throttle plate. They are a "trim" to compensate for virtually any small variations amongst the amount of air leakage across the totally shut throttle plate on Each individual ITB.

But the auto nevertheless operate abundant Using the new one on, then i only analyzed the MAP sensor using a voltmeter, it reveals in ordinary range. For your coolant temperature sensor, i havent checked that prior to as it is hidden deeply back again into your firewall, tricky to reach. But my h2o temperature gauge demonstrates normal readings, so really should i believe the Coolant Temp Sensor is okay?

– As earlier mentioned but with a dyno and an influence operate with and with no solenoid related. There needs to be a significant dip in mid array of the power curve amongst the VVT enabled and disabled dyno operate.

There are actually angular alignment reference points for the timing belt technique in the shape of a small protrusion around the oil pump and the matching notch cut out on the timing belt travel pulley’s rear flange. For no explicable explanation the timing marks / notch about the Blacktop engines are 50 % a tooth / 10 degrees more clockwise than a Silvertop.

Devoid of digging up the BT handbook, I would consider it states that if You need to re-stability the throttles, you must screw each of the by-go screws every one of the way closed, after which you can open the screws over the three decreased flowing throttles to match the very best flowing throttle. This only getting completed In fact four throttles are actually modified to close completely.

To find out the ideal details to turn the VVT solenoid on and off two dyno runs are needed; one particular While using the solenoid locked on and vice-versa. The with each electricity charts overlapped along with each other the best peaks are selected of every of The 2 curves.

I do not know if a person may also help me Along with the vacuum lines for the neater set up. Like what do I need and what I don't will need within the ITB.

Can the vacuum outlet for your eagle be taken from the massive port that goes to the ISCV? Display in the image down below?

The primary difference in toughness is only a factor with larger than first revs, for example OEM Silvertop con-rods are Generally in the position to be revved to a 8600RPM Restrict long term, something that is a great deal not prompt to complete with Blacktop rods. Nonetheless the limit of a Silvertop rod isn’t that much greater right before fastener failure and stretching exhaustion failures ensuing from in excess of-revving appear into play.

I am almost particular that the AEM only requirements the two cam and crank signals if you should run sequential so a 36-one result in wheel should be Alright on its own (make sure you Verify this with AEM)

the second get off is on top rated from the ITB and this is connects to guiding the throttle plate and provides good vacuum (suit the map sensor there)

Only demanded mods are to wire inside of a GM Inlet Air Temperature sensor and operate a vacuum hose with the inlet manifold read more on the ecu.
