Ok so I never did a hertz reading. How do I go about doing this. If there is a video tutorial of this that would be great.

See this explains a lot. What would be the frequency level I would need in the multimeter? I'm guessing bigger then 50 hertz?

Ok so update. Started the car today and let it get up to operating temp. Coolant temp connection seems to be messed up as the gauge didnt work and then after 15 mins of ilding it jumped to mid range and stayed there. Turned it off and car insistently had no power to anything. Check volts on...

Ok gotcha, so as an example a different voltage range of one part could set of error codes. So I went ahead and temporally fixed the headlight issue so I can leave the battery plugged in. Will start her up later today and hopefully at least drive a block or so if she let's me and leave the...

Will codes come if the supra sits and idles for ahwile? In the state the supra is in it wont drive but it can idle.

I just thought of something! So my headlights stay on unless I unplug the battery(will fix that problem later). Leaving the battery unplug, doesn't that erase the error codes? And wouldn't I need to drive the supra to get the error codes to come back on? Cant believe i didnt think of this until...

I opened the ecu and didn't see anything out of the ordinary other then stains in a few places as if some liquid was dropped on it.

Did that and only thing that made a slight difference was the afm which once I unplug and revved up it stalled. But it still acted the same revving up as it does with the afm plugged in other then stalling. But I didn't test the coolant temp though. Could that cause this problem?

Hopefully this used ecu I ordered fixes the problem. If it doesn't I'm at a loss what the problem is.

So according to tsrm all my sensor are within ohms specs. There is no check engine light on. Im getting spark, fuel and air hence car will start but won't rev up. I've installed a used cold start timing switch, used afm, new tps, new starter, new fuel filter. Checked for boost leaks. Checked to...

Ok, so thanks to Toyota's 80's engineers, it's sometimes searching for a needle in a hay stack kinda situation kinda like my situation.

Question, how can my supra be running like this but not throw any error codes? Wouldn't any bad sensor throw a error code? Is there a way to forces an error code to make sure the check engine light works?

And I did check the timing in test mode and it was at 10 BTDC.

I bought it off ebay and he said it came off a working car. I will try the ecu once I get it in and if it doesn't work I will get the proper meter with a good frequency function. But I will need a step by step on how to test with a frequency meter.

Ok I bit the bullet and purchase another ecu. Got it for a steal. Hopefully that is the problem.

Iacv reads at 24 ohms on all b1 to s1,s3 and b2 to s2,s4 Tps reads. Kohms Vta-e2. 0.64 Idl-e2 .5mm. 0.18 Ibl-e2 .9mm. Infinity Vta-e2 wot. 4.10 Vc-e2. 5.37

Ok so I swap out the afm. Still having the problem. I also tested coil packs and spark plug wires. Seems to be within specs. All the spark plug wires were between 2 to 4 kohms and the coil packs were 1.3 ohms. And coil packs are getting 12 volts. That is after running the car for 10 mins. I'm...

Luckily I have an aftermarket exhaust on my car. I need to crawl under the car and see what company it is though. Also have that aftermarket radiator as well.

Ok got the afm in yesterday. Going to install it by tomorrow and let you guys know. What would be the signs of a bad ecu?

So ordering a ecu wouldn't be best idea right now? I might have a great deal for one and might take the deal.
