running a car on e is bad for the fuel pump you could have a fuel pump going bad it heats up and shuts down then cools and restarts check fuel pressure it should be 35 to 40 psi if im correct .a cloged cat would give poor mpg it may be sluggish on take off or will not get out of it own way check the tail pipe you should have a good flow of exhuast .the car has a built in rev limiter it will like rev hi low when it get to the limiterits like it shut the motor down then lets it run so that normal

How Would I check The Fuel Pressure? I Think I know Where but,... I've Never done it before, Just On the Line Above the fuel injectors? And do i check while on?

you need a specil guage for those fitting but that fitting you see is the one you check it on you might rent one from auto zone you get your money back after you return it

Check key on not running and also if possibe when under load.

New TPS has been put in. New coil Which fixed Cyn 3 missfire.

Tps code still comes up with the 5 volt line.

Oh the car gets Good mph or so i think... lol, I havn't Checked the Fuel Pump Yet but,... Today as I was pullin Out the DMV The car shut off, only this time when i turned it back on... EVERYTIME i would press the gas, the car would shut back off........

It Would stay idle but, once i pulled the throttle it would kinda just.... die, No Rev or nothin just die. Then After i did that a few times... The car wouldn't even turn back on just Turned over." Car still Had power though " When the only thing it would do is turn over i heard this noise...... Sounded like aSurge of Power runing off a wire Sparking Off of sumthing behind the motor towards the firewall. I tryed to turn the car on a few times just to hear the nosie and it was going on everytime,.. I sat there for about 30 mins Messing with some wires, then just waited for my freind to come...Btw..... I did DO Alot of driving Today About 50 miles i think On and off, Car only Ran about 210 in the temp.

After about 50 mins i turned the car on and it started up like normaly... Gave it gas and it was fine.....Then drove home like it was fine. ..... No Surgeing Nosie like when the car only turned over...

Fuel Pump Problem ? This really seems like i have a going fuel pump as well,
It does seem like there is an open wire Somewhere:<

I plan on taking the car to the Dealer or just pepboys and do a full dyno but,... That'll be next payday again lol

I really do thank everyone for there time and information. Honestly I can't Thank you enough You're not only saving me money but, helping me learn.

[big white bufflo]

when you replaceds the tps did you adjust the sensor to proper voltage if it out of adjustment it will still throw a code i have done this before and learned from it

[Illegal-racer]

Honestly ... I don't know how to adjst it, And when i used a volt meter thing, it only read like 200+.. sumthin lol maybe i was doin sumthin wrong lol And i didn't test it while tps was connected, i just tested the plug

[big white bufflo]

there is three wire going to it check the two out side wires set the volt meter to dc volt put the black to ground end turn the key on with the tps connected put the prob to one wire at a time one of those wire should give you a reading of less than one volt that is you wire set it to .43 v and that should do it i will look at my buick and see what wire give me that reading tommaro and repost in the morning

[Illegal-racer]

Thank you, Allthough i don't understand how to set it. lol I'll mess around with it tonight.

[big white bufflo]

ok i went and looked at my 92 buick 3800 the center wire is the wire you need to stick the volt meter to .the tps should be slotted leave one screw lose and tighten the other one just enough to move it around one the volt meter put the black wire to ground then stick the other one in to the plug were the wire gose to with the key in the on positionand the plug connected to the tps you should read a .43 volt then to see if you have the right wire move the throtle it should increase in volt then release the throtle .move the tps around to adjust you will see the volts change good luck it pretty simple once you figure it out

I know for a fact that the middle use to give power or.. A reading but, i had only checked it in ohms, I went to check it again on volts and I get NOTHING. I put the black wire to the ground, and The red to the middle one which is light greenish and i get nothing on any setting, If i put the red to the power i do get something, Would the car even start if the middle wire wasn't working ?

I have another question... Is there a way to rig the fog lights and parking lights so they work when the Highbeams come on?.

[big white bufflo]

if you have three wire one of them is going to give you your referance volt im not up on the bonnivilles but all the gm of this body are about the same use your volt probe touch each wire then operate the throttle. the wire you want will be the wire that the volage increases with the throttle movement that how i figured mine out before i got my scanner set the meter to dc volt

[Illegal-racer]

Well...... Seems luck didn't run my way.. Let's forget the TPS lol, The TRANSMISSION........... The car won't drive in first or 2nd gear UNLESS I put it in first and 2nd manully allthough... Its slipin Hard but, still goes very slowly none the less While REVING it's really like they arn't catching at all ..... 3 and 4 are fine, So I think i must be saying my farewells for awhile....
Seems like i need a rebuilt tranny :< = 1,500$$$$$$$$$$$$$$$$$$$$$$$$.
Is there a way to rig it without shifting 1st and 2nd? just like... never shift out of 3rd ahhahahahah... :/

With 134k miles... Is it worth it? Or should i stop before i go toooo faR:"

Thanks again everyone.

ouch thats bad news a tran in michigan is 1400 $ but there is thing you can do before you write it off fluid and filter change is on then then throw a bottle of trans medic in it if the trans is a toltal loss then thy putting in a few onces of brake fluid what it do's to the seales it swells them up but it is up to you some one told me this and i tryed this in my buick tran and it is still going but put the medic in it first it sound like you have a bad modulator or a sticky valve good luck

Thank you for the advice, depending on how much that cost:< i'll do it. and see what happens, I have a feeling like...... ITs just super dirty, it did sit for 1 YEAR with a hole in the bottom off the pan, In vegas which is a desert lol.

I don't think i have ever seen trans medic before, how much would i poor in? and do you know about the price of it? And a few Onces of brake fluid ? lol Thats crazy lol but, i'll do it.
