MAJOR power loss PLEASE HELP
 

I have no power in the upper RPM range. I cannot get over 65 very easily. I cannot find diesel purge so I bought 3 bottles of Power Service Diesel Kleen and a bottle of Chevron Complete Diesel fuel system cleaner. I am thinking of running my tank as low as possible and dumping this stuff all in at once to act as a diesel purge. Also possibly some tranny fluid too? I know people use it as injector cleaner. Please post your thoughts.

Sounds like fuel filters need changed..................when were they changed last.......thats step #1

Sounds like the symptoms I had when my primer pump was leaking (sucking) air into the fuel system. Replaced it and the problem when away. Also check your vacuum hoses - any recent engine cleaning?

I havent changed the inline filter. But from what I can see, it doesn't look too bad. I changed the screw on one last year.

All it takes is one load of bad diesel fuel to clog up the secondary filter. And don't depend on anything showing up in the primary filter. I agree with the doc; change the secondary filter.

unless you have gotten nasty fuel along the way it might still be good........

look for signs of fuel leaks...........many of those can become air leaks under load....................

ANd a pimer pump that leaks when you pump it......if it does re[place it.

Tank breather also..............pop the cap off take it for a spin and see if it still does it.

Tank breather was something I have considered too. I will pop the cap off and try. So possibly the spin on fuel filter is clogged??

How many miles have you driven in the last year.....and how many low volume deisel pumps have you gotten fuel from?

Its a year old so you would not be throwing money down the drain by replacing it now IMHO.

If I replace the filter I replace both of them.

OK So I limped home tonight on the highway... Couldn't get over 30 when going uphill. Had to have my hazards on. Probably going to limp up to the local shop tomorrow and have them flush my fuel system/injection system and change the filters.

You really need to learn to change the filters on your car.

Flush your fuel system? To most mechanics this translates to "Empty my wallet for me please."

What do you think those filters in your fuel system are there for? They catch debris until they reach their capacity and then they quit because they are blocked with debris. When they quit your engine cannot get fuel and it needs fuel to make power.

The whole purpose of this forum is to help people fix their own vehicles. Changing fuel filters is one of the easiest and most basic things you can possibly do.

If this becomes an item that you take in for service, then, I submit respectfully, this forum will not be of assistance to you and you should refrain from posting.

We are all are pleased to help people who will help themselves. :)

did these symptoms happen to arrive the same time as the really cold weather?if so it could be fuel gellin! ;)

For sure. This is a practical forum. If you can't change a fuel filter you are in for some tough times ahead. Perhaps a Toyota would be more your speed. The idea is to exhaust all possibilities by troubleshooting with the aid of this forum, and if you still can't figure it out, well, the chances of 'your mechanic'(always laugh when people say that, like the guy is a member of their personal staff or something) figuring it out are slim. These cars are so very user-serviceable is is a sin to not at least try to show some self-reliance and gumption and fix it yourself. I can understand seeking professional help if you needed a rear main seal or something but a fuel filter gimme a break. You have to have your pasta cut up for you too?
You sound like the perfect customer. No clue, open wallet, like taking candy from a baby.

LOL. This is so true. The repair that happens most frequently when such an individual takes his vehicle to "my mechanic" is the walletectomy. This procedure is very fast, and requires minimal skill, and, the customer usually doesn't even realize that the procedure was performed. :D
