I have never seen those codes on that car. The codes start with a P and four digit number for the engine codes. If you can get me the exact codes numbers I can help you further.

This is the code that is on the scanner screen. I don't want to just start replacing parts, but this all that my scanner says. How would I go about finding out the exact code digit numbers that you are looking for? Where would I find a complete code list? Where do you find the tool that holds the clamps on the air intake tubes. I was thinking about replacing the coil packs and the plugs.
Thanks

The make is Big Banana, the model is BB700. This unit is less than a year old. I will be contacting the mfg. And relay your comment.
What other information do you require? I will be stopping by a place to have a scan performed to see if the same thing appears, will keep you informed.
Thanks.

Big Banana tools is in Austin, Texas. Bigbananatools. Com They claim that this is where the BB700 is made, along with their other models. I have contacted them about this problem and they have not responded yet.
Yes, go ahead and recommend a reader.

What is the tool that is used to remove then reinstall the air tube clamps, that attach to the intake manifold and where can I get one? Snap on, Matco? It looks like it may be a specialty tool.
I was able to obtain the codes. I had to upgrade the Banana.
The codes are: P0300 and P0306. Where can I get a DECENT repair manual?
Will look into that scanner.
Thanks

Those clamps have special tools made by Kent more in the special tools kit for the engine. Very expensive you would have to find a kit on ebay to get the whole kit. But I never used the special tools to do those clamps.I used a small pocket screwdriver to pop them loose and a pair of channel lock end cutter pliers. Let me find the plier number for you. As far as a repair manual I havent looked at the non factory ones.I always had the factory manuals I got when I went to saturn factory training or I used the gm tis 2000 online repair manual.I have used mitchell ondemand and prodemand online repair info. Its pretty good repair info you can buy just the repair info for that car.

Thanks for the info on the pliers. I know I can remove the clamps but could not find a way to squeeze them closed. Will try the pliers. In the event this doesn't work, how about spring tension clamps or regular hose clamps. I have unlimited access to both.

What about the codes?P0300, P0306.
Thanks
