Check your codes and if you get a 1226 it's a knock sensor number two code. If that's the case you may need to replace it. If the code does come up I suggest you swap knock sensor wire one with knock sensor wire 2 and see if it says the the other code pop's up for knock sensor 1.

It would be a good idea to take your Dodge to a competent mechanic to determine what's wrong and what needs to be done to fix it. Otherwise, you end up replacing parts needlessly.

MY 2000 BMW 318I SE IS NOT ACCELERATING PROPERLY WHEN STARTING FROM COLD I PUT MY FOOT DOWN BUT THE CAR JUST JUDDERS ALONG IF I STOP AND REV THE ENGINE PAST 5000 IT THEN SEEMS OK AFTER ALSO THE EMISSION...


There isn't a car out there that likes to be put in drive as soon as it is started. Mine especialy. I give it at least 30 seconds to warm while I am adjusting evrything and away I go. Runs like a champ. Let it warm up for a couple of minutes from a cold start.

Accelerate Problem BMW 1992 318i


a bad camshaft position sensor or a vacuum leak. Most likely sensor. Is your check engine light on? you can test sensors with an ohmmeter to determine if a sensor is good or not. It wouldn't be bad to check and make sure your coil packs aren't bad by checking each plug for spark. You can lay one plug and wire at a time one engine so end probe of plug is fairly next to metal. Have someone crank while you watch for spark.

Temp gauge goes into RED at 3000 revs and/or under load/acceler..


sounds more like a weak spring in the thermostat....not keeping the thermostat open fully under high water flow (like in higher rpms)

Rough idle, Car shakes, sputters and misfires upon acceleration


It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.
