zzp pcm help on my 05

[sp_dynasty]

well i installed the zzp pcm yesterday and did the security procedure and everything seemed to be fine at first. i didnt take it for a ride right away since me and a buddy were installing ssc's but when we were all done takeing it for a test drive it was running very weird. while coasting the rpms would jump up and down from about 650 to 1300ish and it died when i was waiting in line at mcdonalds it died several times but would start right back up and there isnt any codes set off or anything like that. any ideas?? thanks for the help

i have a 98 but the rpm situation seems like the same thing that happened to my car. check the MAF sensor. when i changed that the problem went away. same exact thing happened to my buddies 99. i know yours is a 05 but you never know.

i was looking under my hood and noticed that my intake fell off at some point last night... it fell off after the maf and the maf was still connected to the throttle body but the rest was just hanging there i put it all back together and took it for another ride with no problems but i might be one of those weird things that happens when it wants to

That makes sense for sure.

Reminds me of a similar situation back when i worked at Pep Boys, this girl brought her car in to get a new fuel pump b/c it wouldnt start and thats what someone told her it was...so the mechanic goes thru the whole process of changing the fuel pump, goes to start the car and it wouldn't start, upon looking further into it her intake had done the same thing as yours, the mechanic reinstalled the intake plumbing and sure enough it started right up..... :lolsign:

Ive had similar issues with zzp pcm on my 04 compg. Shifting issues primarily which i guess would affect rpms also. Anywho i dont run it anymore. I emailed them and sent it back about a year ago and they sent it back and still had issues. I said fuck it!. Threw that shit in the trunk.lol I dont even really give a shit about my car anymore....sad but true.

sorry i didnt get back to you zach. im sure that intake tube was the issue, the pcm has no idea how much air was entering so it couldnt adjust the fueling. how does the car run? how did the suspension install go?

 

[sp_dynasty]

dont worry about not getting back to me dan its not a problem... the intake was the problem and its all running great now the install went great and i got the spacers in and now have no vibrations and all that junk...

so i just got done going for a ride and now it wont shift under WOT it just gets to the shift point and bounces off the limiter... it shifts at low and mid throttle just fine tho... im lost on what to do
