When I get in my car in the morning and start it up, I let it warm up for about 5mins. Then I start driving and its quick, but after about 15mins of driving, it will bogg like mad. When I start driving from a dead stop and pin it so its at WOT it will go slower than a old lady driving her 1980 Chrysler Dynasty. And I aint exaderating that at all. But before its completly warmed up its as quick as can be. Anyone know whats up? I have replaced my sparkplugs, fuel filter, plug wires and im out of ideas. Theres no CEL.

compression test

leak down test

go from there

 

chcek your rear o2 sensor. When mine had a short in it, my car drove great until it warmed up a bit and the cat got hot. Then it bogged like mad. Have it checked and replace if neccasary. That is also a good indication of fuel filter, but u already replaced that....

good luck tho

 

Another thing is that sometimes it will have an idle problem.

I have tried disconecting the O2 sensor, still bogs once warm, and the Knock Sensor. And nothing seems to help.

 

Have you ever heard of heat soak? I doubt that would be the issue but i figured itd be worth it to mention. Heat soak is when the engine compartment heats up in such a manner that your intake is sucking in hot air, which your car does not like to breathe in, and could bog abit. just my .002
