CIS Injection | Forum profile

if you manually lift the sensor plate does it spray out of the injectors?

Thank's Steve. I'm already looking into it. The only other thing is with a one way check valve is, will it trap the boost signal in the warmup reg too?

Ignition timing to far advanced, mixture too lean, low octane gasoline or a combination of them. Check the timing first.

Thank you for replying. The intake boots and the plug wires are new..

Before discussing just how to go about doing either, I have to ask why? CIS w/Lambda tries to maintain a correct mixture from idle up to when you really floor it (WOT)(full throttle). When you do that the full throttle switch signals to the control unit to disregards the O2 information. If you convert to CIS basic or alter the Lambda system you will use more fuel during idle and part throttle ...

have you checked/replaced the ISV & or DPR? Ive also had a similar issue and it ended up being the ECU so you may want to check that also.

test the thermo time switch and the cold start injector

I have three 0438100116's and one 0438101005, but no 0438100061 in my supply of parts. Would the 043810100116 or 0438101005 work in place of the 0438100061? Oh, speaking with the local parts place, the guy stated that there are no seals on the push rod as it is machined to seal. Steve

id start by saying to post in the correct forum. then learn about the cis injection! Huzzah!

thanks for doing this, ive got some reading to do

Dang. I would like to have one of these. Are you open to any parts trades?

not to be mean but if you are asking then it is better that you don't mess with it. it is somewhat of a complicated system that can get very confusing if your not savy to it.. best bet buy a bentley and do your homework first..

Won't work, the walbro can't output near enough pressure for extended periods of time. Get a pump from a CIS Rabbit, they're an inline pump with no housing. Why is this your only option?
