Ok so I have a misfire I think on cylinder one. I replaced all the plugs, and its not that. The plug I pulled out was oily, the rest were just normal. So I though it was the wires, nope. Changed them around and nothing. I know its cylinder one that is misfiring because I pulled the wire on cylinder 1 and it runs the same. Pulled cylinder twos wire and it ran worse.

I recently installed this motor from a1993 4runner into a 1985. Everything is hooked up correctly I think. I drove it and its fine just no power and the engine rocks back and forth alot.

So what is it? Timing is off slightly, and I dont know how to fix that. The distributor? Cap? Other options to look at? Seems as if cylinder one has never fired since I installed this motor.. The oil was probably left over from when It was in my truck and turned sideways. The other cylinders burnt it off im assuming.

Doesnt smoke oil, just a little fuel since the gas is bad and whatknot.

Please help!

 

If the new plug didn't work at all then I would check compression on Cyl#1.Might as well check all cyls and see if #1 is low.

 

I bought the engine from a credible source. A mustang performance shop here in denver. Store front type place. I will check compression but what else could it be?

 

Could really bad timing cause this?

 

Timing would likely affect all cylinders, not just one. See if you get any spark out of that wire hooked up to a spare plug and swap plugs between #1 and another cylinder. Might be a bad cap or plug wire or could be a missing or bad head ground wire (located at the back of the head and runs to the firewall).

 

Could be a cap than. I tried the wire switch and plug switch. I will check the head ground. Didnt think about that. Any other ideas? Just getting ideas to try tomorrow.

 

wasnt the cap, wires, plugs or head ground. Any other ideas? Getting my timing done right here pretty soon.

check the plug itself. I had a misfire and went through all the same stuff you did to finally find out the porcelian was cracked on the spark plug itself. Never occured to me since they were new, but hey people do drop things

 

X2 on compression test... could be any number of things

 

Distributor cap would be number 1 thing to check for.

I'm not sure how the EFI works on the Toyota, but an L28-E from a 280z Datsun had electrical plug-ins at each cylinder along the head. My buddy called them "injector plugs" or something. I don't think they were the injectors themselves, but it was meant to time fuel injector squirting with cylinder ignition. These fuel injection systems were the Bosch L-Jetronic models and, from word on this here forum, Bosch also used the L-Jetronic ideas and incorporated them into the "early 22RE's) from the early 80s.

SO. That being said, I would look for what I've just described (a plug at each cylinder, so FOUR similar plugs) and see if there's one near cylinder one that has bad connection (i.e. crooked, broken retaining clip, corroded).

Best of luck.

 

You make a good point, but he did put in a 93 22re, not an older one.
X5256 on check most electricals, tps, simple things

 

I think it's a plugged injector. Buy 1 new injector and try it in number 1. Also, change your fuel filter (pain in the butt to do btw) at the same time.

If you have compression in all the cylinders and you can pull each plug wire and get it to spark against a ground while the motor is running, then it's the fuel. I plugged one of my injectors recently on an almost new DOA racing 22RE and it exhibited the same symptoms that you describe. It happened on my 1985 4Runner after filling up for the first time ever with 10% ethanol....not a good idea on a 20+ year vehicle as every molocule of water and scrap of rust got carried over to the filter.

 

the injector wire is loose on top of the injector. wiggle it while running

 

That's a good idea, if it has compression, and spark it must be fuel problem.I would check the spark by plugging in the loose spark plug and touching it to head while cranking.

 

It turned out it was only bad timing. Well, real bad timing.
Thanks Guys

 

I will be selling this 4runner soon also. I got all the kinks worked out and its rust free. Really a nice example. You can contact me at the below link or you can email me through eBay.
