My 2004 Chrysler Pacifica has been lurching at low speeds. My mechanic replaced the MAP sensor and mentioned that there is a lot of carbon buildup in the engine. The replacement of the MAP sensor has not improved the performance. They also did a top engine cleanout, which I’m assuming is the method …

It depends on who you talk to. Many will say that Seafoam is a gift from the gods while others consider it the work of the devil. Personally I don’t think adding it to your fuel tank according to the directions on the can will hurt anything, but I don’t think it’s going to solve your problem eithe…

Sea Foam has never caused any noticeable damage of any kind when added to the fuel or poured through the throttle here. It is one of several products which do seem to clean injectors and intake ports. It might be worthwhile to try the product before jumping into deeper ($) efforts… Has the fuel pres…

SeaFoam is a great product and will work fine on a problem that actually needs something like this. SF should not be considered a miracle in a can that solves every problem. SF and/or any carbon that comes loose will hurt nothing. Has anyone actually scanned this vehicle for codes or has this all …

With a code reader, and engine analyzer, and a vacuum gage your problem can be diagnosed and solved properly. A can of Seafoam contains none of these things. You need a better shop. Your mechanic is guessing. Skip the Seafoam and find a good owner-operated shop run by a good diagnostician rather th…

Seafoam is unlikely to damage anything, but I doubt it will cure your problems. Just exactly did the mechanic determine there was “a lot of carbon buildup in the engine?” Since neither he nor you can see inside the engine I’d like to know how he came to this diagnosis. Suggesting additives as a c…

Thanks for the responses. To elaborate a bit more, I offer the following. I don’t have a longstanding relationship with this mechanic, as we just moved to the area and only have been there a few times for oil changes, etc. When the car was taken in, there were no codes found. However, since that tim…

Aha! Now that we have clearer details, it makes sense. Yes, P0406 in dicates a problem with the EGR system. Yes, since EGR systems include a small orafice that passes exhaust fumes into the engine’s air instream, they can get contaminated with carbon from the exhaust. It sometimes doesn’t take mu…

And Seafoam won’t fix that carbon buildup, it has to be removed manually. Seafoam will clean any surface that the fluid can touch; injectors, combustion chambers, valves etc but will do nothing for the crankcase ventilation or EGR system.

Safe as you can get. It says, pure petroleum product on the label. To me it means that there aren’t any sea parts in it. I used it in my truck and I think it helped. I even think my fuel economy improved but I forgot what type of driving I did.
