Question about 2002 Dodge Caravan

1 Answer

My check engine light is on. I have changed my spark plugs and cables. I loose power between 40-50 mph. The runs ok, now other problems. The reading stated emission #2 needs to be check ( something to that effect). Please help. I took my car to the shop and they wanted to charge me $16.00 per spark plug. :)

2008silverado 4.3v6 has miss when you ecellrate changed plugs doing it again engine light back on


Since the engine light is back on the code is likely to help you diagnose the problem.
1. If you have a code reader for your car plug it in and it should tell you what the computer thinks the problem is.
Remember for the engine to miss it has to be loosing fuel or spark. The spark plugs are only one of the parts required to make a reliable spark in the plug as the engine is running.
2. Check the spark plug wires and the distributor internal for rust contamination around the reluctor magnet area. The 4.3 chevys are bad for this. Have someone start the car for you at night while you look under the hood for spark leakage. In the dark any wire leaking spark enough to make it miss on acceleration will flash blue lights in the dark.
3. Replace the fuel filter.
4. Check for vacuum leaks in the rubber tubing plugged in to the intake manifold.
5. Make sure the battery to engine ground cable is in good condition at both ends and tight.
6. Make sure the battery to chassis ground wire is connected clean and tight.
Good luck.

I have a 1997 lumina with 3.1L. the problem started with loss of power under load and p0300 code. check coils and vacuum leaks both OK.change spark plugs and wires.[same problem] check compression OK.


Since you changed the sensor we will assume it is working. When you disconnect it you put the computer in limp mode which stops it from using sensor values. If code 300 is the only code we will assume the coolant temp sensor and others are ok.
I would check fuel pressure with a gauge next.

Engine lost all power going 55 mph, check engine light and oil light came on, checked oil level and was good. will not crank at all.


The mechanic should check and repair or replace, worn out or destroyed or burned and loose wire connection parts on the electrical system of the car . from the ignition switch , ignition coil, rotor coil , the starter motor solenoid , the wire connection and the fuses.And check the battery if worn out or corroded ,then clean and repair the battery. The water solution should be check also if not enough water solution then add. If the water solution is dirty then replace water solution.The spark plug should be check also if there is an electricity passing to it if there is no electric passing . then check the spark plug if worn out or corroded , then clean or replace spark plug if needed to be replaced. then check oil light and oil level if needed to be adjusted .Then adjust the check engine will light because of there is a problem in the engine which it can't run because of lock of power. If the problem is in the engine the engine will install . since the problem is lock of power then it is the electrical system of the car. Don't forget to check the sensor its important too.

I have a 2003 vw passat 2.8L while changing the spark plugs I noticed oil in the spark plug holes. After gapping and installing the new plugs I drove the car about 20 mile and the check engine light...


Unfortunately the check engine light could be caused by hundreds of things and yet it could have something to do with your changing of the plugs. Do me a favor and take the car to your local auto parts store and they will check the code for the engine light for you for free. Bring that code back here and I will help you figure out what is causing the light and the slugish engine. Sorry for your problem but I'm sure I can help you get it fixed. Thanks for using FixYa!

generally, when the engine is washed, water gets trapped behind the spark unit and stays there, creating a shorting path for spark plug current. best to dis-mount the spark unit (follow plug wires back to source) and dry and clean it thoroughly.
