The car was fine until the summer of 2006 we replaced the rack & pinion. Got that fixed in Jul 2006. Now here it is Mar 2007 and Now the car has to have a new fuel pump, fuel injectors, and the spark plugs replaced. Also about 8 mos ago the airbag light came on and they can't tell me why. We have replaced the fuses. I love Dodge cars I was raised up on them. I own a 2004 Dodge Stratus and I have no problems yet with my car. But this intrepid is becoming a headache. The idle tension Pulley just fell off. Lucky the car doesn't need that to run. I have kept the maintenance up on this car. Why all these headaches.
Hate to say this about an Intrepid, I love my 93 E/S with a 3.5 engine, but! Check out some of the Intrepid web sites, the 2.7 engine is the last engine you want in your car.
At 90,000 miles it's time to decide if you want to keep this car, or get one like it with a different motor.
I you're a good hobby mechanic you can swap a 3.3 or 3.5 engine in. Get a good one from a wrecking yard and you're looking at around $700 for the engine and a hundred or so for supplies.
If you decide to hang in there with the 2.7 get the best oil you can, and don't put off the oil changes. The big problem with the 2.7 is heat, and the oil gets cooked and forms sludge that reduces oil flow, and will take out your timing chain. Finally, at this mileage, if the timing chain hasn't been replaced, have it done, save yourself the possible bent valves when it does go out.
