Have you undergone the BGBs troubleshooting guide on your signs and symptoms? Again firing isn't always that you will be working loaded. It may be any range of points such as jogging lean.

The engine's AFR appears typical at cruise, but wealthy at idle, as well as the stinky smell tends to make sense Ill if i stay in the garage for lengthier than ten mins.

Using readings from your O2 without the diagnostic port jumped will show you what it is actually reading. This is a good diagnostic action.

I also swapped the oil strain sender from my 7AFE towards the 4AGE BT, it is a bolt in so You can utilize the connector from the outdated harness.

Shouldnt the pressing down closes the throttles and Allow Practically zero air stream thru the throttles? Also, with many of the throttle arms resting on their own theottle stops, how would this allow me to push down on the arms? Is not it presently the tip on the throttle arms? Thank you Jondee86!

With no VVT operational there really should be a big reduction from the mid array electric power. If there isn’t a recognizable reduction then it’s hugely very likely that the VVT pulley is no longer purposeful and wishes substitution.

Incorporate to quote Only present this user #one · Oct seven, 2007 Was wanting to know if accomplishing a ITB set up about the 4AGE is value the value and trouble. I did a search and arrived up with a great deal of 20v data but nothing at all around the 16v... So here are some thoughts I have off the top of my head;

I did utilize the injectors plugs from the new harness, believed they have been merely a little bit distinctive And that i preferred to maintain the OEM body for your injectors plug harness.

The very first-era 4A-GE is nicknamed the "bigport" engine as it experienced ingestion ports of an exceptionally large cross-sectional location. When the port cross-portion was suitable for an incredibly remarkably modified engine at very higher engine speeds, it triggered a considerable drop in lower-conclusion torque due to the decreased air speeds at These rpm. To compensate to the diminished air pace, the primary-era engines provided the T-VIS attribute, wherein dual intake runners are equipped with butterfly valves that opened at somewhere around 4,two hundred rpm. The influence is at reduce rpm (in the event the airspeed would Ordinarily be sluggish) 4 on the eight runners are closed, which forces the engine check here to attract in all its air by way of half the runners during the manifold.

They don't seem to be something that desires adjusting as Section of an engine "tune-up", and really should not be utilized to try and heal other complications.

I are experimenting having an AEM collection one with a MAP 4age, my particular ecu was a plug and Perform unit for just a Mitsubishi Evo VIII and it could operate ok With all the VR signals within the 4age distributor, Curiously the polarity in the VR sign may very well be reversed In this particular ecu.

Thanks Totta Crolla, the vehicle was working excellent about thirteen, 14 AFR just before having a wideband sensor, should i say the ECU could browse the signal then? I would like to be certain if the ECU can study the wideband sensor or not, do you know the way to check it?

The publish ups And large variety of persons which have accomplished the Megasquirt indicate a TON of information around Should you have challenges. Go to the trouble to assemble and master MS and hardly ever glimpse back again.
