Q: for six months i have been trying to help my so fix her mini-van. the mini-van is a 1998 plymouth grand voyager 3.0l v-6 automatic with around 128000 miles. several months back her check engine light illuminated however the car ran ok and the mileage seemed normal. round one - local dodge dealer performed a tune up. mostly new new plugs. light stayed out for a few days. round two - local western auto replaced plugs and wires. light stayed out for a few days. round three - western auto again - replaced plugs again. light was out for a few days. round four - yours truly - used ignition switch method to trigger code read out. got code 43. checked coil resistance compared to manual decided it was not quite right so i replaced it. disconnected battery and the light stayed out for almost a week. round five - used code reader and got p0300 and p0305 codes random misfire and misfire on #5 cylinder. checked plugs they looked fine. i decided that maybe the plug wire was not on correctly. reset light. the light stayed out for almost a week. round six - same codes as before. replaced wires and #5 plug. reset light. stayed out for a couple of days. round seven - same codes as before plus p0306. decided problem might be leaking intake manifold gaskets so i replaced them. reset the light and it stayed out for about three days. round eight - p0300 and p0305 codes again. in desperation i replaced plug #5 with another brand ngk and replaced the o2 sensor with a genuine chrysler part. light stayed out for 3 days but the vehicle did not complete the obdii driving cycle. round nine - dodge dealer again. same codes. dealer performs compression test and says the compression is fine. performs a leak down test and says based on this test the engine is shot and should be replaced - for $4000. round ten - help! $4000 is a lot to but into this van. it is only worth around $4500 in good condition. i am suspicious of the diagnosis that the van needs a new engine. it runs ok. not perfect but no oil usage no smoke idle is little rough but runs smooth at speed. p0305 code usually shows up with a couple of days after resetting the computer. i have certainly driven vehicles that run worse. if i leave the code reader connected to the engine i never see the mis-fire condition. the problem is almost always the same p0300 along with p0305. once p0306 was also found but this was a typical. not fixing the problem is not an option since this is an obdii inspection area. i am willing to try miracle cures...... regards ed white .

what is up with all these pick-up trucks driving around fully loaded or towing with grille/bumper inserts that clearly block 80% of air flow in the middle of summer these aftermarket billet products look cool but it doesnt make sense to block air flow. the oversize grilles esp on the ram and f350hd must have been designed with optimum cooling in mind.. maybe these products should be marketed as winter fronts .
