In the first article, there's a part I dont understand the reason for: «Remove the air cleaner upper case, air flow meter and air inlet boot as an assembly. On SVX, remove the power steering hose tie-wrap on the right side of the engine.» Why do that to remove one fuel injector? Quote Link to comment Share on other sites More sharing options...

frag Posted December 20, 2007 Share Posted December 20, 2007 Cos they're in the way? Brilliant! I was asking cause it's not necessary to do that on my car. I should remember it's not everbody who has the chance of having a 2.2 L engine under the hood. Quote Link to comment Share on other sites More sharing options...
OB99W Posted December 20, 2007 Share Posted December 20, 2007 Before getting involved in further troubleshooting, may I ask how it was determined that there's a problem with fuel injection at #1 cylinder? (Note that I didn't say "fuel injector #1.) Quote Link to comment Share on other sites More sharing options...
mattejb Posted December 20, 2007 Author Share Posted December 20, 2007 Well my car has been throwing P0301, the coils wires and plugs are all good. When I took my car in for an oil change(free) they said they think it must be the fuel injector. I have ran seafoam to see if that helps but the code has came back. So i dont really know what it is rite now. It might be the fuel injector it might not. The car does start to shake when idelling. The rpms hover around 550-600rpm once warm. I am starting to think it might possiably be a breathing problem. The CEL almost always comes on while stoped, coming to a stop or leaving from a stop. Thanks for any help you could give me.

EVOthis Posted December 20, 2007 Share Posted December 20, 2007 i had the same problem.....i searched high and low for the missfire ( in my car is was P0302 =cyl 2 missfire) everything from "dropped valve guides" to plugs and wires, i even hooked up the oscilloscope ......it turned out that the fuel injector connectors were swapped from cyl 2 to cyl 4......now my suby runs perfect.......check that before you go replacing things.....i know on my 96 legacy 2.2 the injector connectors are color coated..... OH, also my miss ONLY occured when i was stopped at idle. i also had a very rough idle. Quote Link to comment Share on other sites More sharing options...

So i dont really know what it is rite now. It might be the fuel injector it might not.[...]Okay, for now let's assume that ignition is okay, and that there's a problem with injection at cylinder #1. Porcupine73 provided good links, and it's probably worth following up on them. One of the first things I'd do is to determine if there's an injector pulse at #1 at idle; you could listen for a "click" at #1 as it operates, or get a set of "noid lights". You might see if #1 injector has a problem by swapping it with another one, and see if the misfire code changes; just be sure to follow the remove and replace procedure in the link that was provided.

mattejb Posted January 9, 2008 Author Share Posted January 9, 2008 Problem seems to be fixed. Front Exhaust valve was tight and binding. The front exhaust valve has been adjusted with a new shim valve. Running smooth, no CEL. What problems could I expect later? Quote Link to comment Share on other sites More sharing options...
