Question about 1989 Toyota Camry

1 Answer

Engine pulsing, poor idle

Hi, we just bought an 89 V6 camry,(144,000 mi) the engine pulsed, idled rough, and tended to die. we did a bearyman's flush through the intake and a radiator flush, since the coolant had stop leak in it (radiator was just replaced). Then pulsing has become less frequent and we now notice it only when idling for awhile or with high rpm's. The heater core is plugged, since the flush we do get a little heat. The vacuum hoses have been checked and a tune up was done. The body and interior are in immaculate condition and the only other problems we've found with it have been a slow power steering leak and rotted exhaust after the O2 sensor, so it shouldn't affect the engine. Have you heard of this before? What could be the cause or causes?

    The spark plugs, cap, rotor, and wires were all replaced...we'll check the ignition coil..

    Question: What was done for the tuneup that you mentioned? Spark plugs, cap, rotor, wires? If all of that was replaced, I would recommend that you replace the ignition coil. Those cars are notorious for bad coils after several years of operation. Please comment back.

Yes, do check the coil, look real close for any hair line cracks on the side of the body of the coil; if it IS cracked, this is def your problem. Hope this helped. Thanks for choosing FixYa!

My 1994 v6 nissan idles rough and has a slight misfire you can barly tell it has one when driving, but when i turn the ac on the idle levels out and the misfire stops. what is going on


Might be the iac gummed up. When a/c is turned on the idle is increased to compensate for the a/c. It might be sticky at slower pulses.

2003 Toyota Camry 166000 mi., 2.4 liter 4 cylinder. ONLY WHEN CAR IS HOT, idle drops off, engine stalls, must step on accelerator to keep from stalling. Otherwise, idles normally. New spark plugs,...


Some "check engine" light in your dashboard? If YES, need to scanned the PCM (computer) to know exactly what fault code is stored there. If NO, the crankshaft position sensor may fail, causing engine stalling or a failure to start. Replacement or the failed sensor will commonly correct this problem.

Also, keep in mind that on the 2.7L V6 and 2.4L 4 cylinder, a defective Exhaust Gas Recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

Stalling synthoms... you can have a plugged exhaust, plugged fuel filter, bad airflow meter, problem with the ignition system, incorrect timing belt/chain setting, and failing fuel pump....I'm sure there's more but that should get you thinking.

Keep us updated.

Where is the cam sensor on a 2005 dodge neon sxt 2.0


Camshaft Position Sensor-On top of engine Operation The Engine Management System (EMS) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The EMS constantly monitors the number of pulses on the signal circuit. The EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the EMS. Some engine management systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the EMS misfire diagnostic will likely be affected.
The following symptoms can be caused by an intermittent wiring connections or faulty signal to the EMS.

  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy

Temp guage inside truck pulses..and outside temp is going crazy...truck is idleing up and down at idle


For the pulsing temp gauge: Check Coolant Temperature Sensor located near the Thermostat.
After this is change - recheck idle.
If still rough on idle, check the Idle Sensor.

Rough idle when warm and in gear, idle pulses slightly every now and then, check engine light is on


It sounds like the timing belt is off a tooth. Did you have it scanned to see what code was in the computer? These engines will surge when the cam timing is off.

Wiring diagram for 1993 toyota camery v6


Does the engine run properly when you drive it? Does it accelerate normally, or does it hesitate & ****? If it runs poor, it may be the wires crossed. If it just stalls at idle, you may have a bad Idle Air Control (IAC) valve, or a partially stuck open EGR valve.
