Car starts and runs but in reverse starts shaking SES lights up and blinks. Have changed the plugs but are getting a P0340. It's an 1998 Saturn 112,000 miles. What could it be?


DTC P0340 will set if the PCM voltage on cylinder #4 signal wire is not pulled to ground (cam signal pulse) when:
Diagnostic Aids
Important: A cam pulse missing may not affect engine operation.
?€¢
An open or high resistance on the #1 plug wire or plug will result in DTC P0340 setting.


?€¢
Inspect the EIS towers and plug the wire connections for corrosion or other signs of poor retention at connections.


The electronic ignition (EI) module supplies a signal to the PCM whenever it determines that the #4 cylinder fired on its compression stroke. Because of opposite coil tower polarity, the simultaneous fir of #1 and #4 cylinders are of opposite polarity as well. Under most conditions, except decel, the waste spark cylinder fires before the compression cylinder in sequence. The EI module can determine this polarity sequence and voltage amplitude by using capacitive pickup plates located under the 1/4 coil. If the module senses a positive to negative sequence and high negative spike when #4 is on TDC, it pulls the PCM cam signal to ground signaling that #4 has just fired on compression. This signal along with the double pulse received from the CKP sensor, synchronizes spark and fuel timing.
Beside plugs , plug wires need to be replaced as well !

How to set the ignition timing on mazda b2600 1994.




  • ADJUSTMENTS







  1. Check engine condition (spark plugs, leaks in hoses, etc.).


  2. Turn all electrical loads OFF.


  3. Warm up engine and run for three minutes at 2500 - 3000 rpm.




Test Connector For Tachometer
Test Connector


  1. Connect tachometer and timing light to engine (white check connector).


  2. Ground test connector (green: 1-pin) with a jumper wire.


  3. Check that idle speed is within specification.

M/T: 750 ±20 rpm in neutral

A/T: 770 ±20 rpm in park

Timing Mark







  1. Check that timing mark (YELLOW) on crankshaft pulley and the mark on timing belt cover are aligned.



5°±1°BTDC



  1. If timing is not within specification, loosen lock bolt and rotate distributor housing to adjust.


  2. Tighten lock bolt to 14 - 19 ftlb (19 - 25 Nm).


  3. After adjustment, disconnect jumper wire from test connector.

95 16v ?
what DTC, post DTC? why skip that,... there are many 02 DTC.
most fail for heater, dead,
lets play a game. say;
1: CEL out running, is it , now?
2: you did the 60k by the book, did you? if not why not?
3: checked spark timing, its good, not way off, is it?
the 60k requires a new Timing belt, ever check that, or the timing of the cam? or compression, if not why not.?
no motor can run right with all or any of those stated items bad.
is the fuel filter packed up. 60k.
lets now pretend the 60k was done and done right.
click 60k here

"what can make my 95 very rich?,"
Ill pretend it's a MPI 16v engine, not TBI. big differences that.
The 16v has 4 injectors, quad trouble !
rich? you never said under what conditions, hot or cold?
ill pretend, its all the time. rich. not just cold or hot.
1: engine never reaches 180F and holds there (miniumum)
does it? if not it will run rich forever. the ECU thinks its cold all the time and guess what it is.
2: Exhaust cracks, near the 02 sensors, making said sensor useless (new or old)
3: fuel pressure not near 30psi ($20 gage) found at 60. opps. bad.
4: leaking injectors.
5: clogged injectors, (seems odd but is true) ask.(complex)
there is an order to finding this.
ask for detailed help here, totally free.

I have a 1990 ford 460 EFI cylinders 1,2,6 has no change or little in RPM when spark plug wires removed.The three spark plugs has black carbon on them. I replaced them with new ones with new wires.Co


check that the egr valve is not stuck open remove it and cover the hole on the intake side and see if it goes away or with engine running remove the vac line from the valve and install a short length of hose and suck on the hose to draw a vac on the valve it only takes 3-5 inches of vac to open it the engine should stall or run even worse if it is not stuck and if it was stuck open you didnt change anything

Vw golf 1.4 16v after changeing timing belt car idles eratticaly or not at all. Timing marks correct at crankshaft, cam pulleys locked as per haynes manual!


The timing could be 180 degrees out you will have to do it all over again. Bring #1 cylinder upto TDC check the distributor rotor arm that it is pointing to #1 plug wire, It is important that the cams are on the intake stroke and not on the exhaust stroke. The crank is no big deal just make sure the marks are lined up.

High idle; 1500-2000 rpm; suspect idle control module?


First I would look for a vaccum leak. Many times a high idle can be the result of this. Just listen for a hissing sound while the engine is running. Sometime it may even be a cracked vaccum line and you can't hear hissing. Use some WD-40 or carb cleaner and spray around the suspected area or hose. If the engine slows down for a minute when you spray you've found the leak.

Have your mechanic check the timing belt marks and the condition of the belt itself. If the cam is retarded a 1/2 tooth due to age, this will create this problem as well. Have him also check for any vacuum leaks at the intake.
