5600rpm sputter

[98gpking]

i posted a while back about my car sputtering at higher RPM's multiple people told me to do a simple tune up so i did the following

new serpentine belt
new supercharger belt
new fuel filter
new spak plugs
new wires
180 thermostat
battery }
}needed replacing
alternator }


before it was a feeling like my traction control was just kicking in so it felt like a series of bumps in the road. now its just one hard jolt. then it drives fine for the next couple hundred RPM's then it shifts and the rest of the gears are fine

if it was still a slight misfire then id feel it in all gears throughout the RPM range. i duno some help would be great

Are you using Bosch spark plugs and ignition wires?

yes bosch 8mm wires.

How about the spark plugs? From my experiences when you get misfire or cutout at that high rpm it is spark plugs or wires. The L36 or L67 SII 3800 works best with the OEM AC Delco.

well before i did my tune up it needed it sooo badly. i use to work in a shop and was taught the max is 6 cracks per inch. on both of my belts i counted 30+ cracks per inch. so i replaced them. the wires were not ac delco so obviously not stock so theres been work done. the pugs were NGK again not stock but when removed were black black black and way out of gap.

Bosch just came out with a brand new plug call Bosch fusion. they were 9.56 a plug so i hope i dont have to go back to stock on those.

but you are recommending i try it??

Bosch plugs and wires are JUNK. Stick with OEM AC-Delco (although NGK makes many Delco Platinum tip plugs, so they should be OK). I'd say its the Bosch wires that are the issue.

I agree 100% on the issue of Bosch parts. For spark plugs try the AC Delco Iridium 41-101 if you are stock. Modded Autolite Copper Core. Third choice Autolite Platinum (AP606/605). NGKs work too.

The wires that I know work with the least problems are the AC Delco Premium Silicone 7mm, Taylor Spiro Pro 8.0mm and MSD 8.0/8.5 mm.

well i got a guy coming over tonight or tommorow to hook up my car to his laptop whatever the issue is im guessing isnt good because my car almost died on the way home and i was only at 4200 rpm. and i wasnt even at full throttle. so im gueesing whatever the issue is its getting worse and needs to be fixed ASAP

or i could just respect my car.....nawwww

Our cars hate Bosch. Stick with OEM for wires, and maybe autolite for plugs. And whatever you do, do NOT put iridium or platium plugs in your car!

I GOT MY CAR SCANNED


AND HERE ARE THE RESULTS

ok heres the results to the scan that i got done on my car. if i can possibly get some further in depth details on what each means that would be great

P0172 fuel trim system rich bank
P0230 Fuel pump relay control
P1363 Ignition coil control low voltage
P1362 IC cylinder 2 not toggling after enable

also we took her for a spin while hooked up and when im open throttle my knock goes up to +6

so we think maybe the size of my filter should be smaller, get auto lite 104's for my plugs and get the ubend delete and it should go away.

Please explain that statement. Why not?

The P1362 and 1363 DTCs is bad news. Do a search on these and see the old posts.

ok im going crazy nothing is helping me. ive been searching all over everything differnt club sites, differnt forums, differnt search engines and all im getting is exaclty what i put up there

so i obviously already know P0172 means Fuel trim system rich bank. but what in the world does that mean. thats like a fragemented run on sentence with 3 different languages.

i need some kind of write up that actualy makes sense to me i had a guy post something on on www.clubgp.com and it made just as much sense to me as IC cylinder 2 not toggling after toggle. GGGRRRRRR

is it safe to be driving my car with these codes going can someone tell me that

DTC P0172 indicates the system is in a rich trim mode. Ideal fuel trim = zero. Greater than zero indicates the PCM is adding fuel to compensate for a lean condition (P0171). If fuel trim is less than zero the PCM is reducing the amount of fuel to compensate for a rich condition.

Here is the course of action per the GP GM service manual:

Check all vacuum hoses at intake system.
PCV Valve
Possible throttle body blockage (clean input screen and body)
IAC (idle air controller valve)
Check fuel injectors (bad o-ring seal)
MAF sensor
EGR valve
Check 02 sensor (before CAT)

On the IC toggling problem it is complex and the remedies can vary from replacing all suspected components to wiring/PCM problems and even a bad CAT convertor. Here are some old posts on DTC 1361, P1362 and P1363 related to ignition control circuits.

sobasicaly all the codes that i threw are not codes pintpointed to a specific problem and need some major diagnosing. it looks like whenever i get paid Pontiac might be making some serious money off me. caused dont know the first thing about where to begin what to check how to check and i dont have a scanner to check if i just did worked.
