By jumping b+ to fp youre basically bypassing the resistor. Have you done the 12v mod? My method of the 12v mod is to simply cut the yellow wire from the ecu to the fuel pump relay that makes current flow through the resistor. At any rate be sure there is voltage going in and out of the fuel...

Check your fuel pump ground while its running. I bet its bad and its trying to ground through another circuit.

Have my 7MGTE running with maft pro(in speed density), 560cc injectors, 36psi fuel pressure( b+ jumped to fp) mainscale set to -20%. My Vf is reading a steady 2.0 volts at idle, perfect 14.7 to 15 AFR at idle, but when i slowly rev up to 1800rpm it cuts out but when revved up quickly it...

just because a noid light doesnt work that doesnt mean the driver in the computer isnt pulling to ground. a shorted injector on a group fire system (2 injectors per driver, in this case) will cause the injectors on that circuit not to fire. unplug both injectors that use the same driver and...

Depends what the emission laws are in your area. In Ontario cars year 87 and earlier don't have to do an emissions test. Oh and Welcome :D

^^that's the trim I'm talking about, I'm not worried about the paint on the trim, but the paint chipping away(shown in previous pictures). I was thinking of just taking the trim off, sanding, spot putty the cracked area and shoot it with some paint, but this problem is all over the...

lol I was planning on doing that this weekend actually, but its the actual cracking paint that I'm more concerned about. Oh and the bottom pic is the window trim(the piece of trim that a part of it is covered by the side mirror).

Now from far away or at first glance its not noticeable at all, and for the most part the paint looks well taken car of(aside from a couple stone chips on the front), but when you looks closely its got this horrible over spray where the body shop decided to mask it off instead of the removing...

Some pics i took a while ago Again, horribly painted rims courtesy of the previous owner lol.:: angry ::

Great job man, looks like a quality build! I especially like the car's stance. BTW how much of a drop is that from stock?

Ok, I see what you're saying. I just wanted to clear up ideas I had, I didn't mean to push anything. So by what the TSRM is saying it is more than likely a fuel issue than anything. Sorry McDewbie, I kind of changed the subject here, didn't really mean to, I'm trying to learn off of this...

Isn't a large vacuum leak the same as having the throttle plate opened more? Its still going to try and keep it at 14.7:1 but its still a larger volume of air and a larger volume of fuel.

The o2 sensor will see a lean condition (provided its in closed loop) and will signal for more on-time at the injectors resulting in a high idle.

I made the point in the sense that the 7mge doesn't have a map sensor so anything after the afm would be un-accounted for.

The 7mge doesnt have a MAP sensor.

A static pressure test? wouldnt you have to eliminate the fuel pressure regulator and the residual check valve as possible sources of dropping pressure?

Tester light by that do you mean a noid light or a test light?(isnt a test light a bad thing for injectors?) I believe both pins should have power as the ECU controls the ground. Looking at the wiring diagram, the injectors are group fired( im inclined to say if 2 doesnt work then 5 wont work or...

My thoughts are vacuum or timing or both. If you didnt time it, did you atleast make sure to line up the notch on the distributor gear as per tsrm? in order words did you set the rotor to number 1 cylinder, with cylinder number 1 on compression?

I tightened up the belt and the squeaking went away, but while doing that i noticed my power steering belt is shot, I guess that's causing some noise. thanks for the reply.

Vehicle: 1989 Supra, 7MGE, auto transmission Problem: Squeaking noise only at idle when all the lights are on, increases with more electrical loads. I checked voltage at the battery while the car is on and it sits right at 14.5v... is this overcharging?Is this normal? Could there be a...
