idle and rich with SES
i have a 95 jimmy with the CPI. I changed the CPI out with a new nut kit and when i put it back togather it wasn't leaking. i started it up and the idle was rough and the SES light was on. let it sit for 2-3 minutes and when i came back all i smelled was the gas and when i looked inside the SES light was blinking. i pulled the ECM fuses and tried again but still rough idel. looked down in the intake and it still looks dry. i did have the ignition on for about 30 mins before put back to check for leaks. reseting the computer doesn't work. what elise could it be?

Re: idle and rich with SES
You have to cycle the key on and off in 3 second intervals to check for leaks.
Also, have you checked your EGR valve? Did you clean the EGR port passageway while the upper plenum is off? All vacuum lines reattached and fastened? Did you use a new plenum gasket?

Re: idle and rich with SES
new gasket,all lines were attached and did dubble check them. only turned the key on once but might pull upper intake agin to duble check. where would it leak. all went togather very well. EGR ports were clean.

Re: idle and rich with SES
There is not set places for leaking. You need to cycle the key on and off for five second intervals to check for the leaks.
Did you insert all the poppets securely into the lower plenum and gave them a faint tug to see if they were lock in place? Is the fuel lines tightened up where they screw into the nut kit? Check the EGR again for plugging. Stop running the engine if you smell fuel because you have a major leak and of course you will need to check it again for leaks. Did you attach all the vacuum line both from and back?

Re: idle and rich with SES
i never pulled it off but it is hooked up. i'm going to go pull the intake now. i don't think theres a leak but i'll pull it to check anyway. all of them made a snap when the went in except for the one under the nut kit lines but when i got it in i pulled on it and it stayed in so i know its ok. let you know what happens. it takes me about 20 mins to pull it.

Re: idle and rich with SES
i thought about it and not a bad idea. not hard to put back on. i noticed that since its been on that the EGR seems to have oily film in it so i'm going to leave it off. i pulled it and it looks fine.pulled the intake and primed it 5 times and still no leaks. i did find a part i forgot but don't think it does anything. it was the rubber boot that sit on top of the CPI in between the ele plug and the unit it's self. do you think that putting it the old CPI is even worth a try?

Re: idle and rich with SES
No, I don't think so.
I would get the codes read to see what code is coming up. Also, did you reset the computer before doing this? How long did you let the truck idle for? All vacuum lines completely attached?

Re: idle and rich with SES
it sat for at least 2-3 minutes. i never pulled any of except the PVC and the line that hooks up by the EGR. they are all attached. i'm going to put the intake back on and i'll try it but if it doesn't work then i'll let it sit all night to clear.

Re: idle and rich with SES
i tried it and its still messed up. when i get off of work i'm going to pull the CPI and put the old one back in and see what happens. I'm thinking that maybe it's defective and the regulator might be letting too much fuel in.

Re: idle and rich with SES
Maybe.....
A defective CPI could be the problem. If you put in the old one and it works fine, you will know you will need to get another CPI injecter under warranty from where you bought it.

Re: idle and rich with SES
Doesn't matter, the code will be still there unless you cleared the computer.

Re: idle and rich with SES
i hope to get it towed today. the guy at the shop said that the computer might have to be rest with a scanner and just unhooking the power might not do it. it sounds like either a plug is not firing or the timing is really off. if it doesn't get pulled then i'm going to pull the plugs to see which are firing. i know the timing order is 1-6-5-4-3-2. how are the cyinder nubers ordered. like looking at the motor. i know its somewhere on this fourm but i couldn't find it.

Re: idle and rich with SES
The firing order is fool proof on your truck with the horizontal cap.
cap 6 5 4 1 2 3 Engine 6 5 4 1 2 3 The wire going to the cap corresponds to the location of its connection to the right cylinder. Eg Back left cap connection goes to back left cylinder etc.....
