For about a week when i start it up to go to work it kind of acts like its going to stall after i get going its fine, last night on my way home when i would give it a little gas it started makin a clickin sound like somthing smackin in the fan, when i went to hit the highway and gave it more gas it got real loud and started makin all kinds of sound, like a chugging sound almost like air pumpin. any one have any ideals what it might be?

 

Might want to see if your valves need adjusting.

 

Might also help to let us know the engine...4cyl/6cyl? Just a thought.
Auto?Manual?
Also, last time since tuneup and by chance do you have an aftermarket air filter?

 

When is the last time you change the engine oil? I hope it's not dried out.

 

I figured it out today now that I had some light to work with, it was the first spark plug, the coil burnt up and the threads where striped so the plug was just setting in there, dont know what caused it, i just bought it about 6m. ago. Its a sr5 v6, auto.
