since youall were so helpful with my last issue, i have another one that might be more up your alley!

the car is VERY slow, not just 60 some horsepower pushing a 3500 pound car slow, it is obviously something out of whack!

it only occurs when the engine is fully warm and when starting from a dead stop, rolling stops do not effect it.

what it does is the engine basically just idles, regardless to the accelerator pedal position. i have had to change my teavel routes so i can deal with it, but now i have a week off for summer break and want to fix it before classes begin again.

the engine runs like a top and, dare i say it, is quiet and smooth. it was purchased in january with 129k on it and i have since put 6k on it to total 135k. will a timing chain effect performance like this? im willing to bet that it hasnt been changed before. but maybe it has, all the filters on the engine were OE, someone cared for the car, but didnt leave the records in the vehicle. so let the thinking begin!

any help would be appreaciated and thanks in advance!

have you looked at the fuel filters?

if the filters have black dots in them you have algae in the tank. if so go to a truck or tractor supply and get algaecide...use as instructed

ive been through that, it was my first adventure with a broke ass down diesel!

i removed the tank, pressure washed it, soaked the screen in mineral spirits and cleaned it with a toothbrush. that cannot be the problem!

as far as dirty filters go, i just changed the pre filter(second time since ive had it) and assumed the big canister filter would be fine(3 small filters to one big one?)

Wrong assumption.

The canister filter, also known as the secondary filter, contains media that will provide the very fine filtering necessary to protect the IP. If this filter gets clogged, the engine won't rev. The pre-filter is there to stop any boulders from entering the secondary.

Change the secondary filter (large bolt on top) and report back.

brian is right on re the large filter...also,


the algae can come from the pump. so even if you did all that, if you got a bad batch of fuel you could be all plugged up again. look for the black dots in the primary filter.
