Yes, i should be more accurate. they did come to conclusion after testing. So this just isnt a regular problem and sounds like its a defect i need to repair. Car is now again inspected and with new cat, it does not NEED the head job... but I am planning to do it to improve occasionally misfiring ...

Looked and looked with search but could not find any info about exhaust valve replacement. none.

My background; been using highway daily driver my -91 parkavenue L27 (no supercharger) from 140k to 190k miles.
I have replaced the cam sensor when the magnet was missing and drove ten thousand miles ...

since it gives a code. concentrate first on eliminating the reason triggering that.
misfire can be almosta anything, a cam position sensor, egr or head exhaust valve burnt. can also be missing magnet from the cam sensor. been there done that. engine quesses the cam position if it does not get value ...

sounds like bigger issue- or just loose connector at bulkhead. i had some problems when i replaced my dimmer sw.
it was my own fault, had attached the bulkhead loose after connecting new dimmer switch wires to that bulkhead. its located at drivers side footwell, main fuse center at firewall if i ...

wow. respect to your suffer. i hope i dont have to do same thing in 5 years...mine is -91

thanks for answers. still wondering on that gear reduced thing;
what does that mean? Delco part with mitsubishi offset...???

according rockauto catalog- this is on example; "pure" delco is with 1.5KW.

ACDELCO Part # 3361441 {#19135295} Remanufactured 4 DOORS; MITSUBISHI Offset Gear Reduction 1.4 KW

hi i have been searching answer for my intermittent slow start sound. so far i have had no problems but starter sort of moans before car starts up.
i am afraid its going since battery is ok.

there is 2 main possibilities; Delco or mitsubishi,
my car is -91 built, without supercharger and ...

similar issues. sometimes does not crank- just like dead, 2nd try fires right up.

last year there was a blown main fuse on Instrument panel right hand side "maxi"-fuses.

could the remote batteries have anything to do with this...going right now to buy new "2016" batteries to it

well mine work, they just now and then keep getting on after turning them off.
kind of funny when they jump lurking like "we wanna wipe more"...

but so far it has cured when i put them back on, and then to off at the highest wiping point

Sorry to steal a topic. mine is 91 but i suppose they didnt learn anything after that, looks similar package. renewing it might be only cure to wiper problems...?

i replaced both front struts with monroe quicks- ...i had replaced the mounts earlier. Do them at same time if they are original!

You might need new mounts, depends if the front struts hesitates in turns. i thought for thousands miles that my brake drags. but it was mount that did not return.

for ...

i would say last bigger fuzz about pontiac over here was the "lunar" transsport minivan of early 90s. it was like moon car, and sold really well, with chryslers voyager. still many around.
enthusiasts dig the firehawks of course... but those were not super-sellers

no matter what they decide to badge pontiac, i would love to see the arrowhead in GM brand selection.
Remember, there is always the possibility future gets BRIGHTER and the differences between corporate fleet gets bigger, not smaller. Hardly own same size engines between makes like in hayday of 60s ...

100 000 miles for stock shocks is quite much.
mine had them first replaced at 80k and now i renew them at 170k. and it was really wawing like a land yacht

clean the core. you need to do it from small hole under the main relay center in engine compartment.
spray brake cleaner on the core and rinse with water. note that water will go to co-drivers legroom.

PRNDL switch?
if its busted, car wont crank

i had similar symptoms- fault was a blown FUSE at right side relay center.
so check the fuses ALSO near the cars brain center (PCM).

did you already change your fuel filter, if its clogged it might affect the fuel pressure?

if it backfires, that hints it gets spark atleast a bit, so it might be with fuel or with ignition control module at "distribrutor"

MAF (Mass Air Flow sensor) is located between throttle body and intake manifold;
here is picture and good how-to-measure it:
