could I just unplug my cold start injector and it will stop injecting? In the instance its leaking, it wouldn't do anything at all once unplugged, right?

or just core yours out.....

cut off the cat and sell it to the scrap yard..... then straight pipe the truck.... cat will pay for half of the o2 sensor. unless of course you have to pass emissions....... then cancel that idea... but based on the condition of your 85 im guessing you dont have that

motocrossaddict223

you can do that, i accidentally left mine unplugged for about a week, so i know it cant hurt anything.

bone collector

yes just unplug the cold start and it will not fire. might be a little hard to warm up in the winter time tho

85gijunk4x4

that's not a bad idea....and yes, we have pretty strict emission laws, actually. But I don't play by the rules never have, may never will

motocrossaddict223

Start with that, its free if you core it out, and cheap if you just put pipe in its spot. But as stated, o2 sensor is a good idea. I got a bosh one, and mine was fine...

Ever change the fuel filter??? no mention of that from anyone

bosch might be good BUT denso is OE toyota only half the price...

85gijunk4x4

nope, planned on doing that soon.

Whoever mentioned cold start injector, I give you props. Went to unplug that son of a gun and discovered a pretty significant vacuum leak on a port the PO tried to plug with duct tape and a broken plastic cover

Hopefully that could be the problem?

Cool about the bosch o2 sensor cuz ive heard nothing but bad things about them. I probably need to replace mine as well. good luck. Remember when you replace the o2, reset the computer too. Otherwise it will still think the old one is on there. Sometimes you just gotta spoon feed the obd I system

YES THAT IS THE PROBLEM!! The comp is reading a lot of air so it is dumping a lot of fuel.... hence the poor gas mileage. NOW GO FIX IT!!

bone collector

It may not be the only problem but it is a big problem that needs fixed

Its all fixed now was a pretty big leak. Still have a funny idle, and rich smelling exhaust. I'll get a new 02, and lean out the afm 2 clicks, then see what happens.

I checked the rest of the lines via smoke test and nothing showing

bone collector

whats the timing set to?? whats the idle at?? did you reset the computer?? if not then it still thinks the leak is there.....

Try to check the colant temp switch...

bone collector

Good luck and let us know how it turns out!!

85gijunk4x4

how do I do that?

idles right around 7-800. Timing is set to 10 degrees, and no I didn't reset the computer, how do I do that? Unplug the battery?

Yes fix the vacuum leak and the broken port. I would keep it set to stock until all the problems are dealt with. Then you can play with it and adjust things.

Silly little trucks, but I still like mine damn!
