Question for @rustybits ... For a 360 Coupe (not spider), it is possible to access the trans heat exchanger through removing the intake manifold?...
Crazy! That explains why the oil pressure didn't decrease even though the big oil leak occurred. I agree with Taz, that's a good catch by the...
Wow, sorry to hear that happened! I'm also very interested in hearing what the shop's diagnosis as well. Spain is a left-hand drive setup (same as...
Yes, dream spec indeed. Just gorgeous! GLWS, would love to see this car come to California!
1300 seems high to me as well. Mine idles right around 950rpm which seems right to me but i guess each car is a bit different. Yes, you can adjust...
Hi Juan. Is it happening at any time or only after you 456 is warm? If it’s happening during cold starts, I’d say switching out the idle air regs...
Very interesting! Thanks for the info, Dave. It's a bit of a shame since I love working on my own cars (the 456 included). No rush since I don't...
Thanks guys! I saw that the P157x codes are mostly related to the immobiliser and that hasn't been acting up at all.
Hey guys, I have a 1997 456 GT and I’m hoping someone can help me out a bit. I have P1578 and P1579 codes appear every now and then that throws a...
Just an update to close the loop on this. With the cats cleaned and the heat shield installed, I haven’t had any high idle issues for a few months...
Yes, you're right they do run pretty hot. I've gotten a before temp but not after...haven't been able to go for a drive yet.
As best I can discern, the Idle air controllers were getting heat soaked from the headers of the car getting so hot! I installed a heat shield...
That crossed my mind as well but my scan tool shows all four of the O2 voltages isolating normally during the weird idling...I'll be checking...
Update: So yesterday, the car started to get the 2k RPM idle without any WOT runs! I decided to take it out and drive nice and easy. The car ended...
Yeah good questions. My guess would be high voltage. Either way, I'm going to clean the MAF connectors and make sure the female alligator clamps...
Thanks, Dave! That helps in regards to the 1514 code explanation. I'm pretty sure the 456 does have the "Intake manifold changeover valve" that...
Hey guys, I have a 1997 456 GT (6 speed, 5.2 Motronic) and I have a weird one that I'm hoping someone has some insight on. A couple weeks ago, I...
Hey guys, happy new year! I have a 1997 456 GT and I’m stumped and hoping someone can help with a CEL code I’m getting... its P1585 along with a...
I'm definitely interested but a little confused...maybe it's me but these definitely look used. There is clearly lots of brake dust (even a...
Awesome! Yeah, I'll take you up on that and will reply via PM.
