I've had this problem off and on for about a year and ahalf. the first time I had the cam sensor replaced, new plugs and wires. this time I replaced the coilpacks and plugs. Still doing it. It ran fine for about 3 months until yesterday where the mechanic pushed in the wires on the computer and tightened the ground. Any suggestions on what it could be??? Could a wire of came loose again???

How much power loss? Is it a constat power loss or intermittent? CEL on?

It just goes in and out. the rpms drop but most of the time the power loss is only for a split second but does it constantly. check engine light comes on and then will start blinking.

If your CEL is blinking, you have serious problems. Did you ever read the CEL code? Any mods done to the car?

the thing is I had my car in the shop all summer and the light would blink but after they messed with the ground and computer wires it ran great until now and started back up. I'm running out of things to change. auto zone computer has the cam sensor and/or electrical problem show up.

When you say ground, do you mean the engine ground or computer ground?

he could of checked both. he doesn't know what he did to fix it but the problem stopped. that is probably why its doing it again. had some people in my car this weekend and could of kicked where the computer is. I believe they said it was passenger floorboard.

the computer is under the passenger floorboard, but there a metal cover over it, so I doubt it could have been kicked. I would check your engine ground wires. Might be a good idea to make a 10 point ground system

Bad grounds is my guess. Just clean up your grounding locations & maybe run new ground wires.

Read the posts above. Try the things this guy did. Cam sensor, Plugs/wires/coil packs, grounding wires, MAF, etc...

What type of power loss are you experiencing?

Usually its when I'm making quick stops on the freeway, engine sometimes want to cut out. Or, when I'm giving it throttle, I'll have a sudden loss of power for a few seconds, then check engine light comes on.

Have you cleaned your EGR valve and also possibly your IAC valve? I would do a good tune-up first-off, if you haven't already anyways. Plugs, and maybe wires/coil packs, check air filter, oil change, battery terminals/grounds, etc...

Yea, I need a major tune up. Just got oil change recently.

Not really sure why you're asking that question when you answered it for yourself a few posts later...

Looks like its most likely my EGR that needs either cleaning or replacing!

When coild packs went on mine they let lose completely. not intermit. Just my experiance. That is why I did the conversion.

Had a coilpack replaced under warranty @30,000 under same symptoms as you described exactly.
