Re: Erratic Idle - If it Idles at All

Here's the instructions from the service manual for checking the egr vacuum modulator: egr.jpg The reason I suspected the egr system is that (off the top of my head and I could be wrong) it is the only vacuum system that is activated only when the engine is warm (unless you have a feedback carb like...

Re: Erratic Idle - If it Idles at All

I'd suspect a ruptured erg vacuum modulator diaphragm. The EGR system is only activated when the engine is warm. On my wagon this happened several years ago. It would idle fine when it was cold, but after the engine warmed up, it would often stall at red lights and idle low. I'd often have to keep m...

Re: fenders

I've never understood how some provinces have vehicle inspections that fail you for having non-structural rust.

Re: 1981 toyota stereo

He also has a (sold) ad for a butchered Cressida with the same stereo in it so I assume that's the car it came from. I still have the stock unit from my '81 Tercel (not installed). It's just a mono AM radio unit.

Re: 1984 Euro Tercel 4WD Wagon

How do you know it's running way too rich? I noticed from one of the above pictures of the engine bay that there aren't the vacuum switches that come with the feedback carb system (like my '84 has). That system has an oxygen sensor and a primitive computer that open and close an air bleed valve to k...

Re: diagnosing high idle

Have you looked down the carb to see if the throttle plate is being held open somewhat? Spray the whole assembly of linkages to make sure nothing is seized-up?

Re: diagnosing high idle

I don't know how high the idle would go if the idle speed adjustment screw was turned all the way in, but it sounds like something is holding the throttle open. I'd suspect a mechanical issue with the throttle plate/linkages instead of a vacuum leak with the rpm that high. Sort of like the fast idle...

Re: Fuel Pump, Filters, Lines Repair Costs

By the way, I'm not sure what an AUC engine is. When I searched online I mostly got the engine code for a 1.0l VW engine. I doubt they'd install anything too exotic in the Tercel wagons. The idea of a Ford trans seems weird too. The automatics in the Tercel wagons had an A55 (2wd) or A55F (4WD) tran...

Re: Fuel Pump, Filters, Lines Repair Costs

Fuel pumps for our Tercels can sometimes be bought on Rockauto for as little as $10, but I think the cheapest one on there right now is about $22 US. Most are in the $40 range. It takes about half an hour to replace one. They do sometimes suddenly fail without warning. My '81 Tercel was driving fine...

Re: funny 1st gen tercel ad

That's a 1980 hatchback too, which is my favorite of the Tercels. The 1980 had slightly different light trim and the Tercel logo on the side compared to the 81-82. It looks like the rear strut towers rusted out completely (which was a recall issue for the 1st gens). I'm trying to figure out where th...

Re: Coolant bubbles

The service manual has instructions on how to check the head and block for warpage. Basically using a feeler gauge and a straight-edge. If the flatness is within spec, then there's no need to machine the head. I did mine a couple of years ago and everything was flat. My coolant was leaking externall...

Re: Which Gear Oil or Differential Oil should I use? Personal Conclusions and discussion. Molybdenum additive use?

For all fluids, I use the specification that was recommended in the manual. The brand doesn't matter to me. I buy whatever is cheapest on sale at the time. Experimenting with different specifications based on internet rumors is asking for trouble in my opinion. I like to think that the Toyota engine...

Re: diagnosing high idle

Wow, my tercel (3-speed auto) doesn't even do 4000 rpm at highway speed. I don't think a vacuum leak could account for that kind of rpm.

Re: Reason for coolant line bursting, not circulating, missing fan?

The fan is on the other side of the radiator so it is not visible in any of those pictures. Which coolant line burst? Sometimes that just happens to old hoses. I'd just replace the hose, re-fill with coolant and drive it and see what the temperature gauge does. If there really is no fan though, that...
