I had my camaro running really good and then i took it and pressure washed the whole enine (bad idea) now it runs really rich. so i went home and ended up breaking off the tbi part where the fuel line goes in. but now i got a new part. but it all pack together. go to start it and i can see a cone coming out of the injectors. not a mist. like there really pumping the fuel. making it rich. smoke pours out of the exhaust. so right now my friend suggested disconnecting the ground on the battery. Maybe in hopes of reseting the computer. does anyone know if this should work. what possibilites it could be. thanks

 

I would definatly check to see if your aircleaner isn't soaked with water, which would let alittle amount of air in and that would cause it too run rich and puff smoke out the exhasut. Secondly you need to check all your fluids because with pressured water it can go in a lot of things. Thirdly check your electrical system, leaving the battery disconnected for at least 2 minutes should clear any codes. If that dosen't work check your pcv system and make sure its functioning correctly. If that dosen't help try to run some injector cleaner through a tank of gas. And lastly check the distrubutor and make sure no water got up in there. Check the ignition, coil, spark plugs, and wires for any loose connections or corrosion that the water could have caused.

 

I appreciate the reply. I found out the problem. I dont' know if you ever had this problem. But the fuel injectors have some really bad orings on them. my fuel injecotor orings where leaking causing access fuel to go in. I already replaced them with ones from advance auto parts but they suck and they stretched causing the leaking again. i got a used tbi off ebay and used his orings and it works better to where i can drive the car. but i still need to get better replacement orings. do you know where i can find good ones. is this something i should get at the dealer. And i really hate this TBI setup for fuel injection. I have an 03 mustang and each cyclinder has its on fuel injector. I wonder if you can convert to a TPI or carb. if any one knows which one is easier swap to do. thanks erik

 

Did you pressure wash the throttle body

 

As long as you use the right o-rings and such, its usually fine. Ive had mine for almost 10 years now, no issues with the TBI itself even as the car falls apart around it. Had it apart dozens of times as well. Are you using oil when installing them? Its a MUST, or the o-rings will be damaged, and the injectors will leak, regardless if its TPI, TBI, SFI, etc.

There are o-ring kits available that have a multitude of o-rings in them. Thats what I did, but it requires a known good o-ring for reference when picking out the proper size. You could also order a rebuild kit, which will come with the required o-rings. Ive reused o-rings that where 15+ years old multiple times without issue, but they tend to stretch after awhile, making them tricky to get in.

 

i bought some new oring from ace hardware. thy fit real tight. I still am not geting a mist out of the injectors. im getting a stream. running way to rich. is there a way to adjust the injectors. this fix is getting frustrating. don't know where to go next

 

It wont really be a mist. It should be a cone of fine droplets at low loads. At high loads, it should be a heavy conically shaped fog. Is your CTS functional? That will cause it to run MEGA rich if its dead.

 

whats the cts

 

Hey what is a CTS? maybe thats it. if not im taking it in

 

coolant temp sensor. did you knock the connector loose? on top of intake.

a trick with stretched out 0 rings is put them in freezer and they will shrink back to original size. gives them new life.

 

Just to be safe, you still may want to check for leaks. Wipe the TBI and bottoms of the injectors dry and place clean paper towels in each bore. Turn the key to the on position, but dont start the engine and wait five seconds, and turn the ign. back off. Wait five more seconds, and repeat this process. Each time, you should hear the pump come on to prime the system. After a few passes, check the towels and make sure theyre BONE dry. If not, its still leaking.

 

i found out the problem. i took it into a tech. he did a diagnostic and found 4 codes. one was the map sensor. which he said can cause it to run rich or lean. another was exhaust running rich, duh. third was cts to high or something. and i forget the third one. hes going to replace all the gaskets on the tbi with new ones from gm then he said the map sensor is getting no vacum. he stuck his finger on it and there was nothing. he thinks someone might have messed around with the vacum lines and there not going where there supposed to be. he is going to get a vacum diagram and make it all right.

 

Just an FYI those ace hardware o-rings may not be solvent (IE Fuel) compatable. Most hardware store o rings are neoprene, or silicone made for water lines, faucets etc. Be sure the one you bought are nitrile rubber or they may swell or shink from the fuel and leak again.

 

yeah i knew the fuel would eventually eat them up. so it was just to see if it would work. but it didn't. He put all gm factory o rings and gaskets. all so far is good. i have no problems and the car runs great.
