Help, no power....

Hey, thanks guys, it's good to hear all the ideas. I did work on the Supra all weekend and came up with some new stuff. I think I found the culprit. First to answer your questions, I did replace the timing belt prior to the install but I've done many in the past. I was extremely careful setting it up right and with the 7M it's as easy as they get. The timing I checked and it was dead on at 10 btdc. I was however able to generate a code by continously trying to get the motor to rev. eventually it crapped out enough to throw a 31. Hanes (cringe) says air flow or ECU. Toyota code book says air flow. Though I had cleaned a grungy MAF already, I decided to go at it again. Upon sterilizing the crap out of the honeycomb, and reinstalling the rest of the assembly, the car revved like normal. I was so freaking stoked! But now it won't idle. Go figure. I guess it's alll good though as the normal symptom for a bad MAF is poor idle. Now that I have seen the changes directly related to the MAF, I am confident the problem lies somewhere within that little black box. 360.00 for a new one seems a bit ridiculous, but neccesary none the less. I need to call around then order one. Too bad there isn't a Supra's only parts store where a guy could get a break on the huge markup. I understand when it comes to aftermarket stuff, but these things can't cost much to make. All the engineering is covered in the cost of the car originally. Whatever, I am on my way and will report after swapping the MAF out with a new one.

Supra chick's dad · 07-17-2007, 08:41 PM

Thanks on the parts leads. Lexas AFM??? Probably not. This Supra is all stock except exhaust mods. Should I ??? I have a lot to learn on these, I'm old school Chevy guy...

supramacist · 07-17-2007, 09:43 PM

Oh you are in trouble Daddy-O.

That's my nic for ya. Don't mess with running lexus parts.
Just make it as mechanically sound as you possibley can.

You may want a new air filter or some plug wires and some hot plugs.
Don't worry about the blaster coil or thw walbro fuel pump or any of that unless you want to.

I think to drive a supra you need a tad bit of ADD so you can do multiple things
and keep switching when you get to stopping points.

Supra chick's dad · 07-18-2007, 02:13 PM

Right now I just want it tight. No leaks no mechanical issues. I might swap out the coils to get rid of all that air in the wheel wells, but it has TEMS and I need to read up cause I don't want to trash the ride. It does have some funky mushroom looking foam air filter now, but it will be swapped out for a K&N soon. It is my daughter's ride so she will call the shots on what we do other than the wrenching. She's learning a lot about that too. She knows way more about Supras than I do, just not whenching. Anyone know the best way to drop a couple inches of suspension with TEMS. I don't like cutting coils if I can avoid it as it jacks the ride.

supramacist · 07-18-2007, 05:14 PM

Eibach springs. they drop 1.6 inches in front and 1.0 inch in the rear.

Cutting coils is not good. I agree.
