I can get back to you on those answers tom. Car is from dead COLD ONLY having a slight delay in starting meaning simply instead of its usual crank rooom its takes not only alittle long but struggles for a sec like crank roo roo roooom not only that today i did some serious high way driving and it seems at times i had to go alot deeper into the throttle alot of times to hold my 75 after alittle bit it would almost catch back up with it self and i had to let up and it would hold and then again at points it almost seemed like it couldnt hold its speed in any position! and YES i do smell gas at times but i was certain it was me rolling the tank seal when i changed the pump agian ill look into my readings tom! Thanks
today i had about an 8th of a tank or so (30 miles to E) i put 3 gal in it and got 30 miles out of it with 15-20 being high way! Very bad!! ive done alot of the poor mpg threat suggests and still have very bad mpg! consisering the quote below do you think a tps could be the cause and what is (If there is) a better way to test???
[quote=”ramman1221101″ post=166145][quote=”ramman1221101″ post=165561] ALSO i was looking at TPS readings today it was 14.9 and i pushed it to the floor got 92 or 94 and let it up for it to read 16.6 this time push it down and let it up to 14.9 and agian to 16.6 and agian and agian where it stayed at 16.6? Whats up with that?[/quote][/quote]Here it is im 99% sure been almost 20 miles and no sputter or CEL! while i was again poking around for vac leaks i put my hand on a spark plug wire and it gave me a static like shock so i warrantied them out and boom gone! I would still like this thread to be open here for at least a few more days just to be sure BUT THANK YOU for your help in all of this!
ok i was checking intake for leaks and i got 1 time (i could not recreate) where the idle dropped off so i changed *UPPER* intake gaskets just cause very well could of been a crack and it didnt change anything i dont believe its only been 5 miles of driving and it seemed alot more on the end of cruising instead of excel but agian have not really drove enough to say that definitively. Still looking into vacuum gauge and fuel trims (i have to drive it for awhile longer reset the computer) Also if i may add if i get on it like really get on it, if i just pop the throttle back off it will like have a rolling backfire noise till i get it slowed back to normal 55-60 speeds. I also dont know if i mentioned it before BUT it was idling abit rough and i change plugs and wires (RIGHT ABOUT THIS TIME IS WHEN THIS STARTED) on the bright side the idle isnt very rough any more! They where autolite DBL Plats
[quote=”college man” post=166177]Your still running lean. p0174 What are your fuel trims doing at idle and 2500 rpm?
I think the next step is a vacuum gauge. I would check for a plugged cat.http://www.ericthecarguy.com/faq/solving-automotive-performance-issues%5B/quote%5D
I’ll have to check here and I can look for a vaccum gauge and hook it up and it doesn’t have cats at this Present time.[quote=”ramman1221101″ post=165561]ok so today at autozone i had the codes read one last time before i went and grabbed an 02 (wasnt gonna change till after i hooked it up to a data read and confirmed) Still same code so the zoner is insisting it is a fuel pump (trying to sell me one) so i went ahead and ripped it out and got my warenty pump and a new filter and change just for the heck of it! NO change in how it runs, i then said screw it and cleaned the maf, nothing changed! so after hooking it up to the scanner and watching the 02s B1S1 stayed in the just below 1 and up to about 950 B2S1 did about the same aside from afew random jumps and drops of course i couldnt get it to act up to bad with it hooked up either way i said screw it and changed B2S1 (due to the random drops and jumps) TADA! Still runs like poopy! next buddy is insisting its IMRC so hell he had a reman IMRC just laying around so i through it on PITA btw! still really no change other than when it warmed up this round it seemed to be almost gone! i cant confirm that till tm when i can let it cool down and warm up afew times! Looked for vac leaks agian! still see nor hear anything and wasted some propane even looking around cant find one!! so im gonna say I have ruled out Fuel delivery up to injectors, maf, vacuum leaks, 1 o2, IMRC. Where should i start next?!?! ALSO i was looking at TPS readings today it was 14.9 and i pushed it to the floor got 92 or 94 and let it up for it to read 16.6 this time push it down and let it up to 14.9 and agian to 16.6 and agian and agian where it stayed at 16.6?

As posted before this and the very first post is what I have done. Today I did codes again an I got p0442 p0420 p0174ok so today at autozone i had the codes read one last time before i went and grabbed an 02 (wasnt gonna change till after i hooked it up to a data read and confirmed) Still same code so the zoner is insisting it is a fuel pump (trying to sell me one) so i went ahead and ripped it out and got my warenty pump and a new filter and change just for the heck of it!

would this current diagnosis cause the car to surge pretty bad? i knew it always had surged but today for awhile it was almost enufff the push through my brakes. i had to apply alot more pressure to them then normal. also its only when im off the gas aka idling but most always its only in gear not in park. that and lastly today it was pulling itself around the parking lot at work at like 10mph even up a slight ‘incline it would take it till it just stopped all together and dropped back to idle. also getting scanner today as long as this dude doesn’t flake on me!!
Idle is fine normal 600ish rpm. Do you think that the sensor could be bad?? i will try and get a scanner to confirm but judging by what you see could you say it could possibly be bad? and that code came from autozone reader and they said it was pcv code. idk either way it didn’t help lol. Aside from a vacuum leak what could cause this because i have searched that thing high and low for a leak and cant find or hear anything abnormal??
pulled the return hose off pump and cranked. nothing came back. if my understanding of how the regulator works is correct i would say there isn’t enough pressure there to bleed it off. thus must be a weak pump. I realize that is sorta a throwing a part at it conclusion. BUT again from my understanding not enuff pressure = plugged fuel filter or line but im gonna say the line really doesn’t seem likely and new filter (yes its on the right way lol). so my only other thought is weak pump? am i right or wrong? right track or not? also there is a regulator looking thing in the inlet line right before the rail, out of curiosity what is it and what does it do? possible culprit?
Also what do you think the odds are its a TCM/PCM Issue? Noticed that my gauges stay floating when the key Is off now also or the very slowly drop to flat
I most deffanitly agree but harnesses don’t just burn up for no reason, correct? So you could say plausibly that it was from the accident garing something wrong? Or do you have different options? I’m just trying to come up with a countrr defense for the aguster (if there even is one). By the way happy late 4th and thanks for all the info so far.
