hey guys,
sorry to start this up again, i thought i would start a fresh thread since the topics kinda changed a bit compared to a few months back..
over the last few months, ive been trying alot of things with my car.
i will recap info about my car, charataristics of driving etc.
Car is a ADM sprinter with a JDM 4age with un-molested loom and matching ECU
1. the car runs SOOOO rich, did about 90km to 3/4 of a tank
2. the car makes a lot of torque betwwen about 1500-3000 (don't have working tacho but at about 30km/h in 2nd gear)
3. the car revs and sounds normal with no load on the engine (in neutral)
4. the car struggles to rev over about 3000 and makes a lot of noise and doesnt go any faster.
5. i just went in a JDM 4age yesterday, and it actually revs and makes power higher up, which mine does not.
is it safe to assume my car is in limp mode, as a few people have been telling it isnt.... :blink:
i can rule out Map sensor as i have bought a new one and tested it, the TPS seems to be working fine, timing is fine, changed the plugs, it made it idle better thats is...
i bought an AW11 dizzy cap, i had to actually drill a hole next to the orginal one which i didnt like doing , but it sits on straight and fires normally and idles even better, but that is is ONLY improvment.
this car is not running an 02 sensor also...(but i am told it shouldn't make to much off a difference, just make crappy fuel ecconomy.
next I'm about to get an ignitor and coil, but i also fear this will have no improvment, so i ask you experienced guys for help again.
then i was thinking about my knock sensor, and is there any way to test if this is working correctly?
Also i went to toyospares in melbourne, and the guy there said "well if you don't have all your factory sensors your ECU's gonna say FUCK YOU i want my facotry imputs and will go into limp home mode, so get a O2 and then it will work"
but I'm not intirely sure that would be the case...
so any imput here would be a great help, ive been saving money lately and if its not working in the next month or so, I'm just going to rip out the loom and either go twin carbs coz i can't be stuffed with EFI, or I'm going to go all out and get Aftermarket ECU and get it all hooked up and tuned..but hardly worth it if my engines remaining stock anyway.....
thanks
