So...Ive posted pics under the Newbie section previously of my Pathy "Romy". Ive rarely had any issues with her since purchasing her, and I drive back and forth halfway across the US due to work, etc. Headed out of Omaha 2 nights ago, started to get a squeal at about 2500 rpm. Turned into a major squeal at 3,000. Figured maybe just a loose belt, and was going to pull off and take a peek at it when the engine suddenly started to run like @!*%. Felt like it just went into crap mode like somebody threw a switch. No gradual decrease, just 100% operation to barely 25%...had the gas all the way to the floor just to get to an offramp and limped it into a gas station so I could do some quick troubleshooting.
Figured out ultimately that the squeal was due to the fan clutch seizing up. Strange ass place for that to happen, but, tighter than a new guy in prison.
Now, on to the next issue...thought the rough running issue may have been ignition related...however I had literally just replaced everything (plugs, rotor, distrib cap, wires, coil) 3 weeks ago...although they can still fail, so, since everything pointed to ignition, got the local "A-Zone" to order the parts for arrival the next morning, so...got a ride to a hotel and a friend who happened to live in Lincoln carted me around and helped me pick up parts...So, I swap out the coil, dist cap, rotor and even dump an alternator into the mix..just in case. Vrooom! Started right up, sat and idled for a while, then I started to head back west...and as soon as the op temp got up higher, performance went to @!*% again. felt like fuel went full rich. Limped it to the Autozone parking lot, made it just before it died...and back at troubleshooting...went through everything I could think of...even down to pulling off the timing covers and verifying that the timing hadn't skipped. Everything was good. timing was perfect. put everything back together. I even pulled all the plugs, swapped out another dist cap and rotor, and threw it all back together...engine was ice cold. (mind you, Lincoln, NE..all work was in 7deg weather with 15mph wind...cold as hell). Went to start...Vrooom! Started up, revved it up to 4,000rpm a few times...ran smooth as silk... until it warmed up...then Whammo...back to @!*%.
So..by this time, nothing left to do because it's already dark and i'm worn out. So, over to a hotel to jump onto the forums. Go through the FSM and try to figure out everything I can, and isolate it to potentially the O2 sensor or the Coolant temp sensor... So back out I go this morning. Nice cold engine, starts up and purrs. I disconnected the O2 sensor connector to isolate it from the ECM, since its freezing cold outside, and once it warms up, we're back to square one...runs like @!*%, degrades then wont run at all. So..before it quit again, and while it was idling, I swapped the connector from the coolant temp sensor onto a new sensor, and voila, the rpm kicked up for a few moments, but it still wouldnt rev, and still ran like @!*%. Took about an additional 3 minutes before it died again.
So..back to square one. No choice left but to AAA it to the local Nissan dealer. (My ass already hurts from the thought). Currently sitting in the service dept waiting room for 2 hrs (when promised it would be looked at within an hour).
SO, I'm taking bets. Anyone care to wager their best guess as to:
A) What is actually wrong with it?
How much of an ass-raping this is going to be in $$
Very interested in feedback here guys.. FAST feedback.
Thanks!
