van runs fine until i step on the gas,it wont kickdown and it just wants to bog with very little acceleration. :| :| i could use some advice

dirty fuel filter, vac line disconnected, very dirty air cleaner filter or bad Karma from not pre-vacuuming.

 

[Mike Draper]

Dirty fuel filter. They are cheap. However,if you burn up your fuel pump your looking $500+ for a pump.

Change your air filter first.

Mine was slow to get going, but a new filter fixed that. I am getting a tune up as soon as I get a day off.

Also you need to check the mass air flow sensor which is right behind the air filter.

a fuel pump for my van is 200.00 so check in the fuel filter is a good idea,while i was on the phone checkin prices,a fuel pump for my 2002 s-10 pickup with a E-85 (ethanol) fuel system,$ 780.00. :shock: :shock: :shock: :shock: :shock: :shock: :shock: :shock: :shock: Ivebeensold Ivebeensold

The pump for the van may also be $800. to install because they have to drop the tank.

First is your light on? If it is check the codes. Second those have a mass air flow meter that is very sensitive. Easy fix though, just spray it out with mass air flow sensor cleaner to fix it. Actually no matter what I would do this. Dust builds up and really affects the way they work. Fuel filter is another should do no matter what. If you step on the gas and it is sluggish it should be throwing a code. Those computers can detect misfires, if your wires or plugs are not working rigtht.

also could be a broken kickdown cable on your transmission

got it fixed,thanks for all of the advice.I pulled the coil and inspected it and it was showing signs of electrical leakin,so i pulled the coil bracket which also has the ICM mounted to it (ignition control module) these should both be replaced together.Coil 30.00.....ICM 92.00 and bam she is cleanin again shiteatinggrin shiteatinggrin shiteatinggrin
