well...I got my 86 running...not idling worth a damn though. Im thinking its a secondary injector thats gunked up, but Im not sure.
so, heres what Im thinking...if I drop in another set of 550cc injectors, Ill be out about $220 if I can find em for $90 and Ill be able to put a little work into getting her moving again, OR, I can get the CAMDEN EFI kit for @$2800 that comes with new injectors, fuel rail, etc etc etc. and be done unnder the hood until I can get a piggyback. what should I do??? bandaid, or full fix? Im eventually going to get that s/c kit cause I want her to out-walk some peeps...lol can someone give me some pointers and direct me to some cheap brand-name parts? you know...injectors, clutch disc, master/slave cyl, brake master cyl...anything I might need after 11 years sitting in a yard, you know. thanks in advance for the help!!! |
If you're sure it's the injectors and you can be without the car for a while, pull all 4 injectors and send them out for cleaning/testing. Marren fuel injection (injector.com) and RC Engineering (rceng.com) both offer injector service for a reasonable fee and can turn them around in about a week. They will clean and flow test them and you will get them back in good-as-new condition.
One more thing: If it's not idling correctly, it's not the fault of a secondary injector, since that injector will only be adding fuel above 3500 rpms. Check engine compression, check ignition, plug wires, plugs, and check for vacuum leaks. I wouldn't put an aftermarket EFI on the car. The stock Mazda fuel system works well and will support some mods. |
yea i'd compression test first. the secondary injectors are off (or supposed to be!) at any speed under 3500rpms
|
Take those 550's out, and put the proper 460's in. Youre dumping way too much fuel for the car to run right.
|
If your only problem is an idle issue, there are a few things that could be the problem, most of which are simple/cheap to fix.
|
well, alrighty then. lol
Ill be sending them off to be cleaned up pretty soon here...they need it, Im sure. after they get back, Ill try to test the compression...*knock on wood* if that goes well, and I still dont have a good idle, out comes the ratnest...I might have a little leak in it...but I cant tell with the erratic idle. well, thanks again for the help people! |
