Thought replacing the brake booster on my 98 bonnie would be easier....geez its a nightmare inside the car just trying to gain access to the booster studs...so far just got the cover plate off...hate laying under the steering wheel...anyone have a magic wand???? The factory book tells me crap!!!!

On my 98 Bonnie 3.8 about 5 weeks ago I got a P1441 that didn't clear itself so I cleared it a day later with the scanner....couple of days ago the P1441 came back..weird thing is both times is both times it came on was right at startup - one first thing in morning, the other in the midst of short ...

I disconnected the maf and of course it threw a 103 code...so I guess the maf is good ? ...guess I'm still looking at a possible egr tube crack..just wish it was easier to get at...just don't understand why maf readings are so low and the short and long term trims were pretty high (16.4) but in the ...

Going crazy trying to pin down this PO171 - - and driving hubby crazy in the process....after we got the engine all back together after the head gasket/valve job/uim/lim - it ran great but the first code was po133 (slow response oxygen sensor 1) we cleared that and then for the last 2 weeks or so ...

When we were checking for vac leaks the other day the engine certainly did rev up when we found a leak...but it just died when sprayed at the egr tube @ the lim...I may try and smear some sort of copper rtv or some such goop to try and isolate it further before pulling off the tb for no reason ...

In this never ending quest of trying to track down this PO171 - I sprayed carb cleaner under the throttle body aiming it at where the egr tube goes into the manifold - - did this 3 different times and every time it caused the engine to die immediately...is this telling me this is where the vac leak ...

Is there anyway to diagnose if the fault of the po171 is due to a cracked egr pipe - such as spraying some carb cleaner near there and listening for a surge?? Just hate to have to tackle the tb removal again unless I'm pretty sure...

Thanks guys,

had the softer rubber end split a little and the hard plastic tubing cracked on me...so far my black electrical tape wrapping abilities have served well for the past year...but it would sure be nice to get a hold of the real replacement....

my 98 bonnie as you may have read before pretty much a good part of the engine was flooded with radiator fluids due to a hairline crack in a tank that started to spew and thus was sucked in thru the intake..wound up overheated and never seen such fried head gaskets...anyway got the heads all dipped ...

After completing the whole head gasket/UIM/LIM we have the front valve cover closest to the radiator has a small but constant drip in one spot on the front that then of course smokes...I'm having a hard time finding valve covers that aren't $200 or so...any ideas?

Thanks,
Melanie

Yay!!!!! ... The 3.8 is almost back together except for the air filter and an alternator bolt/bracket...so we decided to try and start her up - and whaddya know?? turn the key and starts right up with no coughs or hiccups or cels...but there is just a medium loudish air type noise from the TB side ...

thanks for the clarification..sure enough the map sensor just snapped in....did it without breaking the plastic tabs...

in other words, we just wanna make sure that its as simple as pushing/snapping the map sensor down into the 2 black plastic tabs of the pcv valve bracket....just afraid of breaking it..

Still trying to get this 98 bonnie back on the road after having seriously blown head gaskets due to an overheat due to a hairline crack in the radiator tank....cant figure out how the new map sensor we bought fits onto the pcv black plastic bracket...the pics in the svc/man are of no help...afraid ...

Well we finally got it....hubby reworked/rounded the ends of the bolts and that was the ticket....now onto the next insurmountable problem in this saga!!

Thanks again,
Melanie

Both of you guys have given really good ideas....weve pretty much tried these things..seems like everytime we feel like were in the threads we start turning the bolt thinking yay its finally there!! only to let go and have the whole thing fall...hubby is going to try and work/file the ends of the ...

Were putting the 98 bonnie back together after replacing head gaskets, valve job, uim/lim,etc...for the last 3 days both my husband and myself have been attempting to get this dang p/s pump back on with no luck at all....its one of those things where it has to pretty much be done by feel as far as ...

Thanks guys.....went and bought the $10 tool after all because he really wants to be more sure after the last 3weeks dismantling the U im/lim exhaust man and heads etc. don't let anyone tell you this is a no big deal job...some of the various bolts took an hour to get off and that was with pb ...

98 bonneville 3.8.....we had blown h/g due to radiator failure...so just picked up heads from machine shop...need to know how to torque the head bolts...svc manual states tighten first to 37 ft lbs then rotate 130 degrees using a torque angle meter....we don't have one... Is there any other way or ...

We haven't got it totally taken apart yet (weather) but it looks like its gonna be head gaskets...bad compression in 5 of 6 cylinders, 25,35,50,etc...probably due to the cracked radiator that then overheated the car...just so weird since it drove fine the next day after overheating until the tow ...
