Assalam O Alaikom Can anyone guide me about the complete path of +12V from Battery to the Ignition Switch? Not the schematic or Block diagram but the real world circuitry involved. i.e. Junction / Fuse Box, Relay, Fuses... Whatever comes in the path of +12V from battery to IG SW. I own this...

Thanks bro for response and valuable info. Below I am showing you the ECU pinout of my computer connected to my engine, which is 4EFTE. Here I marked in RED that Pin #10 is providing pulse to Injectors 1&3 and pin #20 is giving pulse to Injectors 2&4. My wiring shorted both #10 & #20 with a...

From yesterday, I am working on wiring of my car. Wiring is very messy like nest and no one knows which wire goes where. So I decided to neat it myself because it is a very time consuming job and no mechanic will do it. They like easy money. :) Now I saw some strange issue. Everywhere on the...

I recently installed 04 new tyres (South Africa made) which cost me 187$.

@SKINY I visited the website you mentioned, toyodiy.com The parts are too expensive for me. For instance, Engine main relay price is 91$ and some Cents (Excluding shipment charges) ;) Where as I can get the same OEM made Relay for only 1$.

Hi @SKINY . I am really glad to know that I am dealing with the real "old Toyota" lovers, having no Race/Color/Religion/Region prejudices. We have one passion in common, which is stronger than all other traits. I could gather the relevant part numbers for my car's engine and find them on online...

Oh my Good Lord. For a moment I couldn't connect to this website and suddenly I thought JAY has kicked me off. (because I introduced myself as a Pakistani). I was really disappointed. But then all of a sudden I reconnected back. I am glad that you didn't do that. Cheers and peace to all.

I will definitely try to find the serviceable Waxstat IAC valve there in the ghettos. :)

Currently I am stuck in Karachi for a year. The old parts are readily available in Peshawar (my hometown ) which is near the Afghanistan border. All vehicle used spare parts comes from AFG. Which are extremely cheap as compared to ebay or other expensive online shopping websites.

It was imported to Pakistan and registered in March 2000. I don't know in which country she spent those previous 14 years after her birth. She is with me since 3rd December, 2013. Here she is...

That will be so nice if I get a glimpse of the original manual. Actually this engine swapped by the previous owner. My car is Toyota Corolla 1986 (EE-80). I don't think there is any check connector attached somewhere.

You are exactly right bro. I remember, Once I removed that IAC from TB and found that someone put epoxy in its hole. At that time, I was confused. Now I know that it is done because the Waxstat is not working. Can I replace this Old Timer IAC with the one which has connector wiring?

They are now connected. The engine is breathing through that Cam cover piping to intake. The RPM is very very low at cold start. (Engine wants to stall and Vibrating). But when the engine reaches to its operating temp, the RPM shoots to 1100.

Thanks a bunch. I will study it for any basic knowledge I am missing.

Whenever I search for this IDLE CONTROL VALVE, Google always shows me IAC valve which is right under Throttle Body. The problem is, I got Waxstat IAC valve and it has no connector or wiring out from it. It is a plain mechanical thing and three rubber pipes are connected to it. One is for...

You might have noticed that the PCV valve is repaired with epoxy. Once the auto mechanic climbed on the engine during some repair work and he broke the valve. Since then I am repairing it with glue :). If it is not glued, then engine RPM goes insane high. I want to ask you another question...

To be very honest, I am not 100% sure. I searched for the differences in 4EFE vs 4EFTE but the more your search, the more you get confused. So far I have learnt that Connecting rods of 4EFTE are thicker and Piston heads are dish shaped as compared to 4EFE, which are dome shape. But I can't...

Hey Jay, Dude, I need that workshop manual. Can you share it with me? My email ID is soloukg@gmail.com Your help is much appreciated in advance.

@gv1.3, Thank you so much for posting this incredible information about IAC Valve. From the past 7 years, I am seeing this IAC Valve in my car and keep on wondering what this thing do? I asked every Auto Mechanic but no one was able to answer me. In our country (Pakistan) 99.99% Mechanics are...
