2004 grand caravan driveabilty issue

junior219 · #1 08-04-2008, 11:23 PM

I have a 2004 grand caravan with a 3.3l. it has about 105 000 kms. it has a slight miss at idle, not enough to throw a code. I have absolutely no power, especially for the bottom end. it just lately seemed to get worse. I thought I has transmission issues, so I took it a tranny shop and there was no problem with it. any help will greatly appreciated

Just guessing, maybe plugged exhaust because no power. Have you replace the plugs and wire set? If so, did you ck the plug gap?

I checked the exhaust for a plugged cat. it was ok. the plugs look good. the wires are about a year old. I am stumped

What is your MAP/BARO sensor reading pressure. For here the baro would 29.0 to 30.0 . At higher levels the pressure maybe lower.

I had the fuel pressure checked, it is at 60 psi. the map sensor is 27.00-88.00kpa. I live in vancouver, canada. that is almost sea level.
