emissions

ive read alot of post on what u should do to pass emission tests it seems no 2 people agree on the same thing so that being said does somebody have alist of all related components . to the point were if all were replaced theres a preety good chance your gona pass ive already lost two good cars because of i dont want to lose this one what ever it takes

What part of the emission test did your car fail?
Have you pulled the codes yet? We don't like the throw money and parts shotgun approach to problem. It is usually extremely wasteful. Even if diagnosis can't pinpoint the whole exact problem it can eliminate a lot of possibilities.

I go thru some of the toughest emission tests in the country (IM240 4 gas test) here in SE WI. What I have found is 1) be sure your fuel pressure is at the stock base pressure of 39 psi, or even a bit lower. This keeps it from getting too rich if the tester runs it in such a way that it occasionally goes open loop. 2) Be sure the EGR is functioning correctly. 3) Be sure the base timing is at the stock 10 deg BTDC, or even a little lower, like 8 deg BTDC. 4) Be sure the motor and cat are HOT..... drive it for at least 1/2 hour before the test. 5) if you have a MBC, adjust it (or remove it) so max boost is the stock 9.5 psi WG setting, or if you have the factory boost system intact, put the switch in the regular fuel position.

All this assumes no base engine problems, no codes present, O2 switching correctly, and the cat is not damaged.

A good cat will clean up a lot of problems.

i havent had this one tested yet im just trying to make shure that when i do i dont have problems .this car had three wheels in the bone yard when i bought it i want to replace every thing i can get my hand on i want to take the car back to stock in like new condition so i plan on replacing every thing anyway so i figured id start with the emission system and drive train.i even found a dang nere new dash for it buddy of mine works at a bone yard and i had him watching for parts when in rolls a 88xr7 that look like it just rolled off the show room exept where it got hit on front driver side. i striped the whole car so my interior almost new most of my drive train is new and i want under the hood new as well all i need is an exuse to work on my baby anyway thats why i wanted the list . ive already replaced the egr,o2,tps all new tune up new coil belts,hoses 2optimus batt. 3g alt. most of the wireing under the hood ifigure mitaswell replace everything while i hav the money becuse you never know what gona happen in the future money mit go away and thats when the part will go bad

I don't think you will have to worry about the emission testing anymore. I believe, starting this year, that pre OBD-2 computor cars in Illinois will not be tested any longer. The plan, as I understand it, is to eliminate the dyno testing. I guess they figure there are not enough of the older cars on the road to justify the expense of the dyno testing. I was told this by a couple different repair places that specialize in emission related repairs, an emission test station worker, and there was an article in the Chicago Tribune that indicated the same thing.

Don't forget new plugs and fresh oil.

i wander if thell do any kind of visual inspection.i know that should end a lot of headachs for alot of people

What I heard is that pre OBD-2 is exempt from emission testing. Nothing was mentioned about a visual inspection.
