2004 Dodge Stratus with 75K miles - what repairs might I need?

Could be a problem with the oil pump, the oil pressure sensor, clogged oil lines, or something more major.

Tune up should be done at about 30,000 miles/48,000km on this model car according to the manual.

You have a described an ignition misfire here which can most likly be resolved with a tune up.

On the V6 1.8 hours labor, about $ 150.00 , Parts ? call autozone, Remember to include antifreeze

could your driving habits have changed? or its in need of a major tune up like new air filter new spark plugs,pcv valve ,new plug wires ,an oil change and a fuel filter.

depends on your location and area that job can run from $550- $1200 on high jacking auto repair shops! in my area i usually charge approx $600

Major disassembly of the engine is needed. Errors in the reassembly can cause major engine problems.

Best left to a repair shop that has experience in this job.

i have been in the transmission buisness for 20 yrs in colorado and we charged 225 parts and 150 labor to repair this

The fix is replacement of motor!! I have the same problem and have already paid $700 in repairs to fix seal just to find out that the seal is being knocked out by loose crank shaft..Car had 60000 miles when I bought it 4 months ago, from a dealership, and now it needs a motor replacement..I stiil owe $5000 on a car that is worth $0..Dodge did not give the 100000 mile warranty they love to advertise on TV for the '06 Stratus..They only gave 36000 warranty because they did not think it would last much longer..Will never buy Chrysler product again!! They do not stand behind what they sell or they would have 100000 mile warranty on all their cars..
