Misfire/Backfire and not accelerating properly wondering whats the problem?


1st get a new air filter I recommend a quality brand like the oem one or purolator.
2nd remove and clean the maf sensor. Start with the screw clamp on the intake hose. Then unplug the sensor just squeeze the tab and wiggle it off. Now remove the 4 - 10mm boltsthat hold the maf sensor on the air box. Use caution as some models have a housing with brackets that are loose when the above 4 bolts are removed.
Next clean the air flow sensor using crc maf cleaner or other maf sensor safe cleaner. This is necessary as the sensor gets dirty as the miles accumulate. Make sure the sensor wires are very clean and let it fry for 30 mins before re-installing the sensor.

I would inspect the blower motor for debris as a 93 impreza doesn't have a cabin filter.
You can access the hvac fan from under the glove box see the attached video for how to. I know its not the correct subaru but the procedure is the same. misfire-backfire-not-accelerating-tq5sh21jzhkdedjt044n20r3-4-0.jpg

If you have verified it's an engine problem, not a transmission problem-by noting the same slow response when car is stationary and in park or neutral-then possible the MAF sensor. Clean it with a can of MAF sensor cleaner. If the throttle body is dirty inside, clean that with crc brand cleaner, a throttle body intake cleaner. Check or replace the air filter. If the hesitation is still there, it might be the throttle position sensor. And if still not it, scan for trouble codes and check fuel pressure. Good luck.

Jurking gas smell shifting hard little power when pulling heels


well, there are a few things you can try! a bad tps ( throttle position sensor ) transmission shift issues, bucking, jerking, idle surging,engine cutoff, hesitation on take off, surge while cruising down highway. also be sure your fuel filter is ok! and not plugging up. a maf sensor symtom is surge, slip condition under load, the mass air flow or MAF may be degraded or contaminated. stalling, misfiring, poor acceleration. a light may not come on. you can go to any auto parts store and buy a spray can of maf sensor cleaner. follow directions on can, and this should help alot. good-day!!

Hello,
When the MAF on most vehicles reach a point of preventing the engine from starting, you can usually just unplug it and the engine will start. If that doesn't work-
You may want to try having the O2 sensor, ( Oxygen sensor ), checked. It works with other components of the emission system and can cause similar symptoms as the MAF, including preventing the engine from starting.

Engine light came on went autozone dig read p0174


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Symptoms

You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.
Causes

A code P0174 may mean that one or more of the following has happened:

  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.
Possible Solutions

Possible solutions include:

  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure


Make sure to use ELECTRONICS CLEANER not carb cleaner on the MAF sensor. It looks like a little diode and it is in the intake hose after the filter but before the engine.

Try cleaning the MAF sensor (mass airflow sensor) with some spray brake parts cleaner, let air dry and reinstall. The sensor is located in the airflow duct system leading into the carburetion area and has a wire connection hooked to it. My cousin had this problem on his 2000 4 runner but had to end up replacing his, about $80. Will spin the rear tires now.
