Toyota lists a change from an alloy sandwich plate to a steel sandwich plate around 1989. The steel sandwich plate has some minor internal differences, and it is believed to be slightly stronger (some wider bearings, some wider gears, slightly different gear selection mechanism, etc.). In theory...
MA70T might be your cousin but the STOCK ct26 is probably screaming its little ass off at 21 PSI. Even icing the charge pipes and running an air to water intercooler probably couldn't chill the air coming out of it. Another question, how is he running 21 PSI on the stock ct? Did you weld the...
Setting your ignition timing can cause a high idle as well. When I first started my engine before I fully set the ignition timing it idled around 1700 till I set it to 10 degrees, the closer to 10 it got, the lower it idled.
Unplugging the ISCV causes nothing to happen. You simply removed the power source from it not allowing it to do anything. Think of it as a door that moves when told, if you take the signal away from it, it stays still. When you tried to manually power it, did you follow step 2...
I don't have an AFPR, as I also don't know if the fuel pump is a walbro 255. The previous owner had a ghetto setup AFPR on it so I reverted back to stock fuel pressure regulator. I need to repair the VSV wiring and the O2 sensor just left rockauto.com. If I drill out the j-tube with the stock...
You're referring to a vacuum leak/boost leak. A vacuum leak at idle would cause a lean condition, not a rich condition. I haven't driven the car hard enough to get in positive manifold pressure. The car will rich backfire when revving at a stand still.
It's an HKS ssq vented to atmosphere, I'll be making a recirculation tip for it on the lathe. It doesn't seem to be leaking air in above idle by covering it with my hand.
I meant leaking injector such as clogged or a bad spray but wouldn't a leaking injector cause a bad idle as well? Or only when the injector cycle duty has to go up?
I was planning on getting a spare head and building the head to try and maximize the flow. I figured that a nice set of cams with ferrea dual springs with titanium retainers and shimless buckets with 2mm OS valves intake/exhaust. I just can't understand how the shop says that OS valves can't...
Okay so with a rich misfire, it could be many things. I guess I have to start knocking them off one at a time. I'm not sure what the previous owner has done to the car, it did have a ghetto setup afpr on it, so it could have a different fuel pump in it. Could the walbro 255(If it has one)...
Okay so I found a broken wires to the front VSV connector. I'll report back if anything changes when I get the O2 sensor installed and these broken wires fixed. Does anyone know the PN for the VSV connector? Does it come with a pigtail on it like the knock sensors?
Could you help point me in the right direction to fix this problem? I'm not one to want to be handed things because you learn nothing that way but a sense of direction is always welcome.
