I adjusted my valves on my 22r and she ran great!! But then I took a trip to glamis and the oil got a little low and I heard a weird pop? I checked her out the next day (after putting oil in it of course) and a vaccume line came off of the egr. I put it back on but when I drove home it had little power. I can get to 70 but not on a uphill. Here is a list of work done:
new plugs
new wires
valves adjusted
compression all around 150ish
carb clean
timing adjusted to around 8btdc
exaust leak fixed.
It just seems to have no get up and go....like not enough fuel delivery or maybe a pluged cat?? Not sure where to go from here. Thanks ahead of time for reading this and giving me ideals.


I've searched for hours on this topic...haven't found much....sorry if i'm repeting myself and if you know of a thread then please direct me to it!

How low did the oil go? Enough to loose pressure or trip the oil light on? if you talking a quart or maybe two that really shouldn't hurt anything. I would maybe doulbe check your valve adjustment and make sure you do it when its completely cold. could also just be a secondary might not be working properly causing you to loose power. the secondary on my carb is messed up and it doesnt climb hills very good. If you havent replaced your cap and rotor in a while i would try that. It cheap and can greatly effect the performance.

Try reseting the ECU (pull the battery cable for a while) While you were driving with the vac line off the ECU was adjusting its fuel maps for the extra unmetered air going in the vac line. Reseting the ECU will put it back to the defalt fuel map. Hopefully you didn't blow something while it was running too lean and low on oil.

You did notice the 22R part of his post right?

no oild light. probally a quart to 1-1/2 low!! But at lwast there is a light for that. Now i adjusted my valves when it was warm... i wonder if I should do it when it is cold? I adjusted them and the next day drove 200miles. Like I said halfway through is when something changed. I'll check them again. Any cold measurments available?? And do I even have a ecu with a 22r? I was also thinking about that egr. One cylinder was out for a while (too tight of a exaust valve...previous owner) and i wonder if its letting in too much air. My truck is super lean and I don't know how to richen it up??

Other than that, I'm not sure that the early 85-88.5 EFI system has any learning capacity at all...

It's been pretty rare that I can hold 70 uphill with a 22R series. Could you hold 70mph before this issue? Was compression checked before/after the oil incident?

efi...22r...maybe i'm missing something...

LOL

Yea something is blocking/not entering my enging performance. could be the valves. How do you guys set the valve clearance??

dont do your valves cold! do a search and you'll find plenty of people that tried it cold, and couldn't get em to work right, including myself.

Oops, never mind then.
