1988 ford festiva emissions control schematic

We have a festiva that needed smogged. The smog place said the pipe from the small manifold by the carb was missing and needed to be installed. The catalytic converter has no provision for a connection, although the muffler shop ordered a replacement that did have a connection for the pipe. I am trying to find out if this was a midyear change as our converter was the original and there was no way to connect it to the manifold by the carb.The service manual diagrams for the 1988 do show a connection from this manifold (control valve?) to the converter.Any help on this would be appreciated. Thank you

    Have you owned this vehicle from day one-new? The parts look up does indicate a converter with an air tube fitting and associated air tube for the 1988 model. There are after-market (universal) converters that would not have the air tube fitting, but would fit on the exhaust system.

Whatever it had when it was sold in OR is what will be required in calif, it goes by engine calibration number, that is on a sticker on the valve cover, another way to get it is to run the VIN number on a Ford information computer, we call this the OASIS SYSTEM. Also check the emission sticker on the radiaor support under the hood.

SOURCE: HCL too high, did not pass smog check.

ok well this might be a hard one . from what i can gather by the co reading and the o2 reading is that we are running fat. a couple things can cearte this one how many miles do we have on this mtr, two do we have a vacuumn leak? three is the vech going into closed loop? some how we need to get are hands on a scanner so we can look at a data, other wise you are going to be throwing parts at this vech , and thats not the way to fix your problem. the odds are that you may have some lazy o2 sensors you are close. have you tryed running the vech down the road before you go in for the test. the converter is like a hot water heater you have to bring it to operating temp before it will operate correctly. keep me informed

SOURCE: 1991 Honda Accord LX failed emission test on smog

not enough info. Typically, CO and HC together can be the result of poor fuel control or misfire, or worn components such as O2 sensor or catalytic converter, but without more data, repair recommendations are likely to waste money and not achieve success.

I just bought a 1988 Mitsubishi Mighty Max it failed smog due to tail pipe smoke when you you Rev it up and egr function fail how do I fix it so i can smog it I know it burns a little bit of oil

You could rebuild it. stop the burning oil( this is a fail). Or dump it and upgrade your vehicle. Another option is to move to a place that doesn't have emissions testing.

Fuel gage not working

Charge light could be due to Alternator starting to fail or maybe loose belt to alternator. Or loose connection at alternator or at battery. Check wires along the circuit path and make sure everything is tight.
As for gas gauge, you may have a bad sending unit which is usually IN the tank or a bad connection between the unit and the dash. I'm not aware of a working gauge being a necessity for passing emissions but maybe so.

Did the 1988 Chevrolet 1 Ton come equiped with a smog pump

Yes they did, and I used to maintain a fleet of them for a certain lath and plaster business in the mid 90's and most of them that I serviced were from around 1987 to 1988 and all of them had a smog pump, and I also had to make sure that they all passed a bi-annual emission inspection.

Need to figure out where my vaccum lines go off of my carb on my 81 cj7

on the radiator support, you'll find the vacuum diagram , easy as a road map to read, for some. If this is a replacement engine, go with the basic line configuration of; vacuum advance, automatic tranny vacuum line, temperature controls if vacuum operated, fuel tank canister. Don't be surprised to see you can block a number of vacuum fittings off the carb. If emissions is an issue, you will want to google the info. List the name, make, model and search on google for the vacuum diagram

What does my 77 gmc K20 need to pass CA smog

As far as I know. Anything 1994 and under don't have to go through emissions anymore, just safety. But, like countrysi248 said, it might depend on what state you live in. Best wishes to ya.
