High RPM Miss

[dangerranger83]

But probably not good with emissions though. You can buy lead addtitve but I think it is a substitute though. Just buy octian booster.

I plan on the additive called
HEET
which is higher octane

To prevent fuel lines from freezing up or something... i have heard great things with that and smog...

Should pass though

Carb rebuild
o2
newer cat
valve stem seals replaced
intake mani cleaned and gasketed...

Im hoping anyways!

 

[dangerranger83]

It should pass, if not get the carb tuned then. First things first smog test.

 

[Eric Kropp]

So where are you sitting with the miss and smog stuff?

[TheNicky]

Still driving it just making complete sure that miss is gone...

and so far so good...

ill smog it this weekend im thinkin!

If you're not sure, ask them to pre-test it without sending the info to the state. Otherwise a failure is reported automatically and that can cause problems with registering it. You may want to try a station that can do repairs and have them test it at the same speeds that you need to pass; a good tester can tell you what you need.
Good luck

I know.. the thing is i think the truck went through 2 owners who had little knowledge of how to wrench on a car and what was goin on with the truck so they gave up...

and i know that the guy before me smogged it 2 times before giving it to me both a gross polluter...

SO this shall be fun then.....

and its hard to find a decent smog tech + mechanic!

hey paul know anyone here in sac?

 

[dangerranger83]

I wonder how they tested your truck in 1983 and what it took to pass then. You would think it would pass. There no way it will be able to pass todays strick standards.

 

[enginepaul]

Sorry, don't know anyone in Sac.
As for how these trucks passed in the past: all they tested was idle and about 1,500rpm, the functioning of the EGR and a visual. Now they do a dyno test, no idle.
About all I can add is: (tips from a smog referee) change the oil and air filter and PCV valve immediately before the test. I also clean the hose and PCV filter to be sure there is less carbon being sucked in.
Incidentally, test only stations and the referees can not give you advice, they are only allowed to say that you passed or not. One smog guy didn't disconnect the spout connector and flunked my truck. When I went back with a page from the Ford manual, he said it didn't matter because he was 'trained.'
I wish I had better news, but that's the way the State does things now. Keep us posted. (I was on Arcade Boulevard at Marysville Road off 80 yesterday)

 

[TheNicky]

They disconnect the spout for smog tests?

And just as a refresher... i disconnected it did my timing and then plugged it back in? is that correct?

becuase now with the timing advance its way off specd?

and ok so
oil change
pcv filter
clean out the hose
air filter
and high octane...

should be good then...

The spout is there so you can set the timing to a KNOWN setting that the computer relies on to advance the timing from that setting. Likely you will never see the same timing with a light after the spout is reconnected.

Haha thats what got me i plugged it back in and then looked and i was like WTF...

Cool thanks jim

But they do disconnect it to smog? how wierd?

 

[Eric Kropp]

OK, for starter...DON'T "just get it smogged". If it is hooked up to Sacramento and it doesn't pass, it will be deamed a gross polluter and you will be required to have a full diagnostic done at your expense on the vehicle if you plan on driving it. Did it do the high RPM miss before the carb was rebuilt? I agree with the dudes that it sound like a fuel deficiency. I would look into the fuel pump. The fuel pumps on these kind of suck to replace. Some times I would cut an electric one in and see if that clears it up. The only bad thing is that Rangers have no rubber in the fuel line to install one easily. California Smog is concerned with emissions and how it looks. It has to look exactly like it did at the factory. All the tubes, hoses, pre-heaters etc. If it has a miss at the 2500 rpm test, it may or may not pass. They always warm the engine up real good to get the cat. conv. good and hot. I have seen some shops that if it has a miss they would not even try. I have seen some shops that are real cool and would see if it will pass before they hook the dude up to Sacramento. Sacramento is our State Capitol. When a vehicle is smogged it is hooked up electronically to the DMV in Sacramento and they know if it passes before you do.......

They disconnect the spout to check timing; then they put it through the paces. It has to have base timing and all things connected, although mine passed without the cold air tube connected to the air cleaner inlet.
As stated above, make sure it is warmed up before taking it in; if the guy wants you to wait for a test, ask if you can drive around and come back. Mine make a difference when warmed up properly.

 

[dangerranger83]

There is a rubber fuel line on the Ranger. Its under the drivers side door. I hope this truck passes.
