okay so i have a 1990 bonne sse she used to run great bout three years ago, lots of power always peeled the tires when you wanted it to never had any idel probs nuttin. so okay bout three years ago it got a gas leak in the sending line so the car just sat in my driveway for about 2 years then moved in with my mom had it towed to her house it again sat in her driveway for about 1 year then i finally got around to going and fixin the gas line. i got the sending line fixed and it ran okay took it for a little spin and she died on me couldnt figure out way. so i took it back to the house and it sat all winter (the one we just had) snow finally melted away and i whent out there and checked some things out turned out all three gas lines where cracked so i had to patch them up, then i found out that my fuel filter was bad whent to go replace it and my line broke on me so ever since ive been goin without a fuel filter. i just recently moved to east lake and didnt want to get it towed so i started to check things out again ended up haven to replace a tire and had to run it without my maf for about 200 miles or so. well ive been workin on it alot got it runin real smoth other then the fact it badly needs a muffler and desided i wanted to get rid of the stubborn ses light so i had to fix my maf got the maf fixed but runs llike crap always stallin so i whent out and got a hanes manual and got to work ended up havin to clean my air intake manifold and it ran better but had no power i mean you could floor this thing and it would take like 1 minute to get to 45 then would creep up to 55 hold at 55 for miles and you would have to use hills to get it up to 60 (mind you this hole time your florrin it) so im lookin all over tryin to get the power back ended up comin across some kind of tps optimization on here and tried it omg it was great got all my power back and more but it would have problems idlein when its cold and sometimes it would idle at about 2-23oo rpm but hey i didnt care i got my power back . but then i couldnty take it no more and wanted everything right so i adjusted the tps and got it to idle at 15 out of gear and 1 in gear but it would end up workin its way back to 2000rpms when idelin so i kept adjusting it finally got it going decent but then she got to about 180 degress and i shut it down tryin to adjust the tps more and whent to go start it and it would roughly idel at about 500 rpms and die if i give it gas to keep it runin it stays at about 500rpms but still dies well thats all i can get for now im actually surprised ive wrote this much pls hlp me if you need more info i will be glad to give it to you my dads in prison it was his car and i would just love to go pick him up in 3 or 4 years in this car

Woah.


Three years ago it had 1 bad fuel line.

Last year you fixed one bad fuel line.

This year you drove it 200 miles without a MAF.

This year you replaced three fuel lines.

You adjusted the TPS and it won't idle right.


Did you fix the MAF problem?

How are you adjusting the TPS?

Did you allow the PCM to learn?

Have you reset the PCM?

Have you checked the cat?

yes i fixed the maf and yes i let it learn drove it around the block a couple times also did the whole key on and key off just like it said i havent realy checked my cat but from what im told it would smell like roten eggs

What is the idle voltage of the TPS?

okay theres a prob with that i am very broke and have almost no tools. i know that i took a flat head screw driver to the side of it and i would give it little taps left and or right till i would get it just right.reason bein after i fixed the lines and started drivin it again it would not run at all with the maf hoked up so i disconected it and with doin this it is finally starten to run with it and not really putin out any codes exept for after awhile it will give me a code for a quad driver module circut i have a haynes manul and cant find anything about it

Okay, You don't have the tools, materials or funding to fix it. Your TPS is badly misadjusted, Your MAF may have wiring problems and your exhaust backpressure is too high.


Where do you live?

eastlake ohio, my girls father has a 90 buick lesabre and she was drivin but but tore up the front end and fried the tranny so hes suposed to b givin it to me so i can fix my car but just incase he doesnt im trying to sorta fix everything i can without really spendin money so far ive only put in 10 bucks for new plugs that really helped till i hoked the maff back up then everything just started all over again

WIth the MAF disconnected the engine is running off a guess and it isn't always right. This explains why it doesn't like to rev. That'* a very important sensor.

Maybe you're just not experienced with FI or something, but disconnecting sensors long term is not a good idea.

A new engine will not fix your problems, It will only complicate them.


Here'* how you should fix it:
Get a volt meter, adjust the TPS properly.
Get to a scantool and verify that the MAF works.
Get an exhaust backpressure guage. Verify that it is within normal limits.

Here'* some poor redneck tips:
If you have a welder, cut the exhaust off in front of the cat to see if it runs better. If it does replace the cat, If it doesn't weld the cat back on. If you can't get to a scantool, Buy a MAF and try it out. If it doesn't fix the car take it back. If it does keep it. Look at her car and put your TPS as close to where hers is as you can.

the maf is fine i got it off her car tried hers on mine to see if there is any dfrence and there was where as with my old maf you hook it up while the engine is running and nothin happens hook hers up and the engine stalls out by the way if you can plz sign in to yahoo its so much easier for me have the time i cant remember what exactly we are talkin about

I'll be on yahoo in 5min.
