Question about 1995 Honda Civic

TPS Sensor bad? Car idle jerks when A/C on only

When the A/C is off, the car runs fine. The moment A/C engaged, car drives like your accellerating, then decellerating. Back and forth. It is driving me crazy and my MPG is really bad now, about 25 MPG.

Hope I described it so you understand the symptom.

Car jerks sometimes when going from P to R


It's the transmission sensor. I've had mine replaced three times now. You can fix it (see this thread: http://www.suzuki-forums.com/suzuki-forenza-reno-forum/35284-transmission-range-sensor-all-you-need.html) and please report it to Suzuki at 1-800-934-0934

Check for vacuum leaks on all hoses underhood. Make sure all intake componets are intact and they are tight.

Is the check engine light on? If so, get to an auto parts store, they should pull the codes for free.

Sounds almost like a bad throttle position sensor. The computer uses the TPS to help know when to shift on this car if I remember right, and if the TPS is bad, it can cause that jerking. Along with the car dying when slowing down after driving. But check everything else out first. Including electrical connections.

check out tps sensor it has a big effect on shifting of vehicle. The data provided by TPS is invaluable for proper startup, idle and easy throttle response of the car. These operations are affected when a bad throttle position sensor feeds erroneous data to the car's computer because of which the:
  • Engine malfunction indicator light (MIL) is turned on
  • The driver of a car experiences difficulty while changing gears.
  • The fuel economy of the car drops drastically.
  • Causes difficulty in setting base-ignition-timing of the car a bad tps causes transmission shift issues, bucking, jerking, idle surging, engine cut off, hesitation on take off, surge while cruising down highway. it may not be that but try another one and find out. you can test the tps, just unplug connector to it. use a ohms meter and hook one lead to the top and other to the center prongs on tps itself. next move throttle very slow, if good tps will move needle on ohms tester it will sweep up without cutting out. but if you perform this test and the needle hesitates at any time you move throttle plate it is bad. 1 is ground, 2 is signal, the prongs on tps. good-luck

After driving and warming up the engine it hesitates after you come to a stop. engine idles fine but push the accellerator and it take a few to sec. to go. 2004 murano


You may want to look into your MAF (mass air flow) sensor. Or it also sounds like a TPS (throttle position sensor). Both can cause the same thing. If you put your A/C on full blast while in drive and you foot on the brake you may have a TPS problem. Hope this helps and please rate me.

Try exchanging the MAP sensor from the other "good running" car. What I think you are experiencing is a flat MAP which fails to read more than the minimum. A MAP sensor out on these cars will make it run absolutely terrible and die as you have indicated.

By unplugging the TPS sensor you are effectively putting the car in "limp" mode. In this mode it ignores a potentially bad TPS, O2, and MAP sensors and or circuits.

Jerking on normal acceleration.


You might try a TPS switch. It should set a code but yours did't. The throttle position sensor sets the spark advance and fuel flow to match. The other possibility is the EGR system which also should set a code.
If you have not changed the fuel filter,try that because if you accellerate hard the fuel slooshes to the back of the tank.
In normal driving the contaminents lay on the bottom of the tank.

wqithout looking at it directly , could be neglect to the car it self, clean them batt, cables not just the outside of them take them off the battery . clean the right , ck the wires make sure thay are also not corroided , as for the running like **** , sounds lik maybe a vacuum line came off , could be bad sparlk plugs wires etc, if it just happened in a spur of the moment thing , I would ck those vacuum hoses , something like tha will make it run like you are saying , tune it up , plugs and wires etc, clean it so you can see it .listen for any strange noise and do be carful
