Mk3 Turbo Problems

[cre]

52's common enough. The wires running from the knock sensors to the ECU degrade and cause too much signal loss... that's the most common reason for that code anyway. One or both of the knock sensors could be bad. Do a search here or over at SupraMania for "knock sensor rewire"... there are a couple walk throughs posted. This code may be solely responsible for your idle issues... and once corrected the car should run better in all cases. This code causes the ECU to add a lot more fuel and pull a significant amount of timing as it operates in a "safe mode".

The code 43 is another thing. having any trouble with your starter? If your starter functions fine and you're not push starting the car this code is, again, most likely due to faulty wiring. I'll post more info for you later, but basically you need STA at the ECU should be at 12v when the engine is cranking... if it's not the ECU can act odd in a number of ways.

i was looking around and it might be the alarm that disable the engine, cause when i lock the car, and then open it back up the alarm goes off until i put the key in the ignition, i don't have the factory key so i am guessing that might be and issue to

Please take a little more time in the composition of your posts. It makes it a lot easier for us to accurately help and makes it less of a chore for us as well.

As for the battery, are you saying that it keeps ending up drained? If so, even if the original problem wasn't simply a bad battery, the battery is probably shot now. Check for parasitic losses when you've got a fully charged battery connected. Shouldn't be more than a few hundred milliamps of draw.

The most common replacement for the stock blow off valve for a car that's stock is a certain model Bosch bypass valve (aka blow off valve). I don't know the model myself, but you should be able to locate the specifics easily enough by searching "Bosch BOV" on most of the Supra sites.

With the power steering the problem could be any number of things. A bad power steering rack, and clogged line, a shot power steering pump, emulsified power steering fluid, or even a bad belt. For more info on trouble shooting the power steering system look here: MK3 TSRM On-Line

ok up it turn out the alternator fine, my and my brother was tinker around with th afm and next thing you know the car fired up, i took to a speed shop today he said he found oil,on the spark plugs and it was missing the gasket to prevent that, the guy said he was gonna due a complete tune up and let me know any other issues that come up

Ok here's the update, i took my car to a speed shop to get my car checked out and fixed and he found a couple of problems, one the spark plugs had oil on them due to a lack of a valve cover gasket so he had to clean it up and reseal my valve cover, and the the timing was WAY! off cause the car probably ran so bad because of the half ass build up he the former owner had to set the time off just to run the car so he set the timing back, the wiring harness is screwed up he patched it up but he suggest i get a new one. Now i need to know where can I find a place to buy a wiring harness???? beside a junk yard
