SR20DET S13 Problem!!!!!!!!!!!!!!!

mrx7255 · #1 10-25-2004, 02:33 PM

My friend has a SR20DET S13 Red Top and he's been having probelms with it. When he starts to drive the car it starts to buck and the exhaust is really loud. The first thing we did was check for leaks but there are none. Then we started adjusting the TPS (thorttle position sensor) and it worked. The car ran perfect for about a half hour or so. After that it started doing it again and now with a new TPS and clip for it...it still doesn't work. We look at my SR20DET and ajusted it to that but no good. Now I don't think it is TPS.....

Any ideas????????????????/

buck, and ehaust is loud, thats all??????
the discription is vague, but check you fuel, it might be sending more fuel in than needed. not realy sure, is there a spike or drop in rpm, is the the rpm needle moving up and down, is the motor shaking? and does it do it only when he is taking off or even when idling?

We checked all the Injectors and test them with a multimeter and the fuel pump.

The car feels like there is a lot of stress being on it and it can't go fast. Around 2500rpm the car won't stop buckin but it passes as the rpm's go up. Thats why I thought it was like a dead spot in the TPS but I don't. Also after you go go past like 5,000 rpm it picks up speed fast.

Thats all that happens with the car.

You might want to check you distributor, and ignition system, sounds like a spark problem, not 100%, I ain't that good at diagnostics.

Yea that be it y0!!!11doh!!!11

have you checked the MAF and its wiring?

His SR20DET doesn't have a distributor and the cam angle sensor was tested and so was the MAF.

Every freaking car has a distributer, whether it is mechanical or electronic, under electronic you could have the single coil packs over each cylinder, or the single unit that all plug into. You could also have like the pontiacs dist which uses a coilpack for every two cylinders. BOTTOM LINE, every car has some form of distributer.

Unless he somehow did all the wiring straight from the battery haha. Your right man. EVERY car has a distributor.

so is it fixed? what happened?

mrx7255 · #10 10-27-2004, 03:16 PM

We can't figure it out so he's probably going to send the car to paisley automotive they can fix the car no problem they are just alittle expensive.

Thanks though

DIS

Distributorless Ignition System.........

also back on topic... put your MAF meter onto his car and see if that helps.. it sounds like that is the problem... same sorta thing happened when my brothers Maxima's MAF got wet. I am about 90% certain the problem is electrical and involves telling the computer how to run the engine, if its not the MAF look for other sensors, wires, and the actual computer for problems...

let us know what the problem is when u find it

ahhh.......... no. sr20's are distributorless and have coilpacks and a crank angle sensor.

go to www.freshalloy.com advanced section, people are more knowledgable there.

if you said that you fooled around with the tps and it worked, then it didn't... sounds like its your tps. just try to find another one and plop it on. other than that it might be your timing.
