hey all. I was driving at 55 mph when my car started surging and exhaust backfired a couple times just like a car running out of fuel. the tach wasnt jumping so I figured it wasnt crossed wires. It hasnt shut off on me yet but it does it after driving several miles. before winter I changed fuel filter plugs, cap,rotor, and coil(it went bad) so Im assuming f/p if anyone thinks different or have any other suggestion please help. motor is jdm h22a 66k miles and body has 220k

 

so it idles fine?

 

idles perfect. its 20 degrees here so it idles high at 1500rpm durring start-up then of course comes back down to normal

 

does it start actin up at a certain rpm?

 

It just started today but it seems to do it in any gear any rpm. but when I pulled over and sat there in idle for a minute or 2 i drove it home(4 miles) with no issues I just want to know should I be preparing to get a f/p soon or could it be distributor

 

if it was the fuel pump it wld affect your car all the time not randomly, and the dizzy wld cause missfires, i wld start checking sensors

 

like what. this is very sudden.

 

what is sudden? umm check your maf, and check your timing, fuel filter, o2 sensor, and you can check your dizzy to see if its adjusted correctly, oh and vacuum leaks

 

never happened ever. I was 10 miles into my trip when it started doing it. also where is the maf. I have a sensor on top of my throttle body that is unplugged with no wires next to it.

 

did you just take that pic now lol? that is your tps sensor, you shld probably plug that back in lol

 

it has never been plugged up since I bought it. plus its a swap so it has no wires running to it on the harness. I thought tps is the sensor on the opposite side of the throttle lever and is controlled by the throtte shaft??

 

oh well if it was never plugged in its irrelevant then

 

MAP sensor (manifold absolute pressure)

 

anyone know how to wire the map.

 

I want to say that there are a couple of vaccumm ports just right of the sensor that are connected as part of the throttle body, might be unplugged as well, which Im pretty sure would cause vaccumm leaks.... Idk just a thought...

 

im going to connect my fuel guage and look at as i drive so if pressure drops its the f/p let you guys know tomarrow
