1994 Intrepid 3.5L running on 2-3 of 6 cylinders

[tyrael2304]

I bought my 1994 Intrepid 3.5L in June of 07 and I had the engine replaced. The mechanic who put my EGR valve and regulator in said that my car was only running on two or three of the six cylinders. Does anybody have any idea what that could be? He claims he's checked the wires and the fuel pump. And just last thursday, he was able to get it running great and then it wouldn't start up on friday. I would really appreciate anyone's suggestions as to what it might be. Thanks..

Can you give us a description of what your mechanic has all checked on the engine or replaced? IT could be a number of different compotents causing a no start. Have the codes been checked, if so what are they??

From the explanation you have given I tend to believe it may be the coil pack, it is a coil pack that has three coils in one, meaning 1 coil of the pack supplies spark to 2 cylinders.

Also if the crankshaft sensor or camshaft sensor are malfunctioning the engine will not start.

Go to the online service manuals posted on this forum and it will give procedures to test coil pack, camshaft and crankshaft sensors.

Keep us posted.

I suppose that would help huh? Sorry about that. The only thing that he's told me that he's checked are all of the wires around the transmission and engine. This guy is usually pretty good with these cars. My fiance and her family have brought him six other intrepids. But thank you for the suggestions. I'll be sure to call him at eight when the shop opens and ask him what he's checked. I'll definitely make sure that he checks the camshaft and crankshaft sensors if he hasn't already and I'll let him know about the coil pack as well. Thank you for those suggestions.

You can pull up codes on you car by turning your ignition key on and off three times real fast and watch your service engine light it will flash like 5 times one after another then another 5 times meaning you have a code 55 which is normal then it will pause and go into your problem codes it will give you the first # then pause and give you the second # when you find out what the code is look it up and it will tell you if it is a crank or cam sensor problem, this helped me when i had a crank sesor problem on my intrepid and it fired right up! if you find out the code get back to me and i can let you know what it is.

Trouble codes for all Intrepids 1993-2004
GA_googleFillSlot("Forums_ROS_300x250_noad"); Hello everyone,

I've created this thread to help out those who have a Dodge Intrepid or any Daimler-Chrysler vehicle that was built from 1996-present. If you have a check engine light and need to know what the code is, visit this website to give you the answer(s) to your code issues. The website is:
http://autorepair.about.com/cs/troub...l_obd_main.htm.

If you have a 1993-1995 Intrepid and you have a check engine light, you can find out what the codes are by following this process:
1. Turn the ignition key on/off 3xs ending in the ON position
2. Watch the "CHECK ENGINE" light and see if it flashes.
3. If it flashes twice then pauses and flashes again another 4xs, that's a code 24, for example. You have put the computer in diagnostic mode and it will now display any codes that have been stored in memory. Here is a list of all codes that can be displayed and what they mean:

12- Problem with stand-by memory circuit. Direct battery input to controller disconnected within the last 50 ignition key-ons.
13- Indicates a problem with the MAP sensor pneumatic system.
14- MAP sensor voltage too low or too high.
15- A problem with the vehicle speed sensor signal. No speed sensor signal detected during driving conditions.
16- Loss of battery voltage
17- Engine coolant temperature indicating engine temperature cold too long.
21- Oxygen sensor voltage not fluctuating.
22- Coolant sensor voltage too high or too low.
23- Throttle body temp sensor below acceptable parameters.
24- Throttle position sensor voltage too high or too low.
25- Automatic Idle Speed motor detects a shorted condition in one or more circuits
26- Peak Injector current has not been reached.
27- One of the injector control circuit output drivers does not respond properly to the control signal.
31- Problem with the canister purge solenoid circuit
32- An open or shorted condition detected in the EGR transducer circuit.
33- Air conditioning clutch relay circuit open or shorted.
34- Open or shorted condition found in the speed control vacuum or vent solenoid circuit.
35- Radiator fan relay circuit open or shorted.
36- Problem with the air switching solenoid circuit.
37- Open or shorted condition detected in the torque converter unlock solenoid circuit.
41- Problem with charging system. Voltage below 11.75.
42- ASD (Automatic ShutDown) relay control open or shorted.
43- Engine misfire in one or more cylinders.
44- Ambient/Battery Temperature too high or too low.
45- Transmission temp sensor not indicating warm condition.
46- Charging system voltage too high.
47- Charging system voltage too low.
51- Oxygen sensor signal indicates a lean condition.
52- Oxygen sensor signal indicates a rich condition.
53- Internal PCM failure.
54- No cam signal to PCM.
55- End of code message.
62- Unsuccessful attempt to update EMR mileage in the controller EEPROM.
63- PCM failure. EEPROM write denied.

These are all the codes for most 1993-1995 and a few 96 and 97 Intrepids. If you need any others if I missed them, please let me know.

have you checked your distributer fuel injectors if is equipped you mau just need a new distributer check thoes first any simple thing you can think of check it it could be something right in front of you and your just over looking it
