Quoted From techhotline7:
follow Erics video on a/c diagnosis or a/c leak detection. I forgot the exact name of the video, however, there is a possibiltiy of a leaking evaporator if you are smelling engine smells. If you are smelling fuel, then that could be an entirely different problem. The clicking of the a/c compressor is the clutch engaging and disengaging due to either improper refrigeration charge, or possible bad pressure switches (if applicable)
I figured it was the clutch engaging and disengaging but couldn’t figure out why. I have a feeling it’s a refrigeration charge issue simply due to the fact that so many things had to be removed in order to get to the timing belt, including moving the compressor out of the way, back and forth, etc. Can you tell me where the evaporator is? I’ve looked at vacuum diagrams but can’t seem to make heads or tails of them. And I did watch a video from Eric on A/C leak issues but when it came to my particular truck, I just wasn’t following it too well.
Quoted From rice400:
The evaporator is in the dash, check under the hood for where the ac lines go into the firewall. Thats where the evaporator lives
Great. Thanks so much
Quoted From rice400:
get a hold of a fuel pressure gauge and see what kind of fuel pressure you’re getting when the engine starts to misfire
Thanks. I’m gonna stop and get one tonite. My first thought was something to do with the fuel mainly because of the way it boggs down and the fuel smell I sometimes get with the AC on.
Quoted From EricTheCarGuy:
I hate to tell you this but you really didn’t eliminate a problem with the wires if you didn’t do all of them. Here is a video on checking for voltage leaks that might help you determine if they are indeed bad. FYI I often find on transverse mounted engines only the front spark plugs get changed and when they come in with a performance problem I change the rear plugs and the problem goes away.
http://www.youtube.com/watch?v=x-U9WqJfaJsThat said you might also check for an exhaust restriction by perhaps removing the O2 sensor and taking it for a drive, if the problem changes or gets better then perhaps you have a restriction in the exhaust somewhere. Lastly check your transmission fluid level and condition if it’s an automatic, you might have a transmission problem.
Yeah, I figured as much with the wires. But I work 7 days a week and can’t chance having to dismantle pretty much the top half of the truck to get to them! Just afraid there’s not enough time. Thanks for the video link. I’ll give that a try too. The rear plugs are the ones I really want to get changed but pretty sure I’m not that mechanically capable of doing it. Problem is I work 7 days a week and really have no time for car to be in the shop. I travel an hour each way to work so by the time I get home it’s getting too dark to start anything and have it finished for tomorrow’s work day.
I am certainly going to do the 02 sensor check. Thanks for that idea. Unfortunately I have a 5 speed so the simple transmission fluid idea doesn’t seem like the solution. Wish it was though. Sorry I didn’t mention that earlier.
thanks again for your ideas and I’ll give them a shot.
Quoted From rice400:
do you have a check engine light on?
Nope – but I just found out the problem! Driving 70 mph on the 5 mile bridge crossing Lake Pontchartrain timing belt popped. My new question is – can it be fixed or is it one of those like zero clearance engines where I should have just dumped it in the Lake and not paid the tow fee??
Quoted From rice400:
i believe its a non-interference engine so there shouldnt be any engine damge
Thank you. That is the news I’ve been waiting to hear! I did check some sites online and they said the same thing but I believe this site much more! Again, many thanks!!!
Fuel filter replaced about 6 months ago (what a pain that was having to use a special tool!) Air filter and plugs replaced about a year ago. I’ll get the fuel gauge and see what that shows. Thanks for the tip.
Yes, I know why there are 8 – even though it’s unfortunate that I can’t reach 2 of them without basically dismantling the top of the engine! I really don’t have the time to do that in case that MIGHT be the problem. I’m sorry but I don’t know what a CEL is.
Sorry – you were talking about a check engine light, right? No, there is no check engine light on. I hooked up a diagnostic check that I bought from Auto Zone anyway but didn’t find anything.
Thanks DioFan – Yes, it did start after the coil spring replacement; however, the replacement happened back in April of this year and this just started fairly recently (about 2 weeks). Could it still be that the springs are not seated correctly? Again, when the springs were broken it didn’t do this – it just leaned to the left a lot. Other than that, it drove okay.
WOW – so I’m not crazy! Thanks Eric. I can’t believe you actually replied. I figured you’d be way to busy to reply to my topic but I’m glad you did! If it’s okay, I’d like to add just a little bit more and answer dreamer’s questions as I could really use some help on this (thanks for the input dreamer and thanks for the welcome aboard!)
Engine is 2.5L and 2wd. Type of parts I really don’t know. I had a shop do the suspension stuff and I did the ignition stuff but I got it from my local Advance Auto Parts so I don’t really remember. I did not see any print out for alignment. When I drive it, it does not pull or drift to any one side. In fact, the steering wheel does not even shimmy. However, it just seems like the whole truck is sort of “floating” – for lack of a better term. It just always seems like I’m in a very windy tropical storm with winds coming at me from all directions. Sounds strange, I know! Truck idles really fine. Another thing I wanted to add was that when I am driving, my passenger door shakes and I can hear it creaking, squeaking, squealing – whatever you want to call it. It does not happen on the driver’s side and it never happened when I first bought the truck. The door lines up fine and opens and closes fine too. It seems to be a symptom of this “bouncing” up and down I feel like on the road.
Just today, I had the differential oil checked and it was perfectly fine. I do not see any leaks of any kind anywhere in my driveway. I like Eric’s suggestion about the suspension mounts and I am definitely going to check that because it makes sense. I really wasn’t putting much stock into the performance issue because it really idles nicely, no leaks, and not bad gas mileage – it was just sort of a hope because I can work on engines but not so much on suspension. I would really appreciate any additional thoughts before I start poking around tomorrow. I’m taking the day off to try to get something done because I travel 85 miles a day to and from work and really want to find out what’s going on. Thanks again to both of you.
Dreamer – thanks much. I have checked the weatherstripping on the door. It seems fine. I’m just saying it seems to be shaking and rattling because of whatever is going on. Leads me to believe whatever the problem is it might be on the passenger side of the truck. I appreciate your help and I am going to review that video first thing a.m. when I’m ready to begin my search. It’s raining here now and has been most of the evening so I wasn’t able to get out there on it tonite. That’s why I’m taking off tomorrow. I’ll re-post if I find anything or if I decide I’m just crazy. LOL.
