I have a 1995 dodge ram 1500 5.9 automatice 2 wheel drive and it dumps gas into the carb with a code 37 coming up. could the intake gasket cause this problem? i have replaced the coolant temp sensor, the iac, beggining to think the ecm might be bad, any ideas?

That is an ABS (antilock) ccode. I am adding a post that has some information on it.

This truck has problems with the cover inside intake leaking vacuum and causing rough idle and oil usage , its hard to say what your problem is with out testing, have you had the check engine light scanned for codes? what year is this dodge?these also had intake leak problems. try starting the engine and let it idle and then with some carburator cleaner spray around intake gasket and see if idle changes if it does then you have a intake gasket leak, another problem may be a leaking injector, try some sea foam in the gas tank and run a half tank of gas and see if that helps, otherwise a fuel injection system cleaning would be the way to go but this is only if its an injector problem, if this truck is 1996 or newwer have the computer scanned at an auto parts store for any codes. if there are codes let me know what they are even list the code and #. good day

P0138 DODGE - O2 sensor 1/2 Circuit highhttp://engine-codes.com/p0138_dodge.htmlForum CodePossible causes- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Rear Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks Tech notes Replacing the rear O2 Sensor bank 1 usually takes care of the problem.

The intake manifold gasket may have a leak, the unmetered air causes the lean condition.

intermittent lean condition may be caused by leaking intake manifold gaskets. Get some carb cleaner and start the truck. Open the hood and spray carb cleaner on the intake manifold gaskets. If the engine reacts at all, you have a gasket leak. If you have questions, please let me know.

you have a leaking intake mainifold gasket that is common on the model

there was an issue with plate on underside of intake coming loose and causing vacuum leaks and rough idle

SHOWING MISFIRES ON SCAN TOOL?IF NOT,ENGINE CONTROLLER HAS NOT LEARNED MISFIRE MONITOR..WILL HAVE TO BE DRIVEN A BIT FOR RELEARN..IF YOU CAN SEE MISFIRES..MISFIRING ON MORE THAN 1 OR ALL CYLINDERS?CHECK UNDERSIDE OF IGNITION COIL FOR CRACKS..IF NOT CRACKED,YOU MAY HAVE A FAULTY CRANK SENSOR..ANY CORRODED PLUG WIRES AT DISTRIBUTOR CAP?ALSO CHECK IF ANY OIL PRESENT IN INTAKE MANIFOLD..GASKET ON BOTTOM OF INTAKE MAY BE BROKEN CAUSING AN INTERNAL VACUUM LEAK

pan gasket on bottom of intake manifold may be leaking internally and causing oil consumption..remove air cleaner housing and open throttle plates and look for oil pooling inside manifold..if so..intakw ill have to be removed and all gaskets replaced

those sensors could cause the issue, clean the MAF 1st, also clean the idle system using the following procedure, the IAC can cause cruise surge. I use this to cure these problems all the time.

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve (IAC) and throttle valve, they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
