Thread: throttle problem helpp video inside winner gets $40

Set you tps voltage, idle control, and try setting your ignition timing to 15* and see how that drives for ya, if drives good then set your timing 17*. Check how that drives. Heres a video of my tps voltage don't mind the way its running, it was trying to lite 100 psi of fuel.http://s891.photobucket.com/albums/ac119/xavi1320t2/?action=view¤t=firststart.mp4
Again don't listen to the way it runs, but you can see the voltage being put out by the tps sensor.

tps at .30v closed should be around 3.96v-4.00v wot. Take our advice and call us in the morning. Sounds like your igntion timing may be a little off as well if it's popping and stalling. Unless the thing is super super rich.

Can you slowly put the gas to the floor and watch the rpm's climb to redline? Or does it cutout around 3500 rpm's every time? Slowly rev it instead of blipping the throttle everytime. I think your maf is wired incorrectly or you have the wrong maf on your tune.

which wire do you hook it to on the TPS? i want to test mine.

White is the 0-5V signal.

A good idea would be to put a consult cable and logger on there to check all of the sensor readings.

The chip is definitely programed for the right MAF as it was still the stock B13 MAF, I just checked the bin file that I sent you last.

Did you test for vac leaks (these can cause high idle and everything you are describing)? How do you know there is spark? How do your plugs look? Is the rest of your ignition wires,cap, dist all good?

And you should keep your money. Everyone here has asked (or at least has been free to) for help at one time or another. That is what this community is built on. If anything donate it to Crim or who ever is hosting the site now to keep it going.

Ok so the tps and timing is now set properly and and I can rev it fine at idle but now when I go to drive if I gradually bring it to speed in 1st gear it'll be fine it'll rev to 4500 buy when I shift to second gear no power

Update: when I put the car in first gear it try's to stall when giving it gas then catches it self and goes I can get it thru all the gears but it starts to lean out like 16-17 on the lc1 and doesnt boost

What happens when you rev higher than 4500? Breaks up? Check some of the things I asked about. You are skipping steps and that is going to make it harder to diagnose your problem/s.

your timing is too far advanced it sounds like. Mine was at like 19* one time and it felt like the car was NA.
