Replying to: electricdesign (Sep 30, 2009 5:29 pm) I appreciate your concern. As I mentioned in #475, before I left New Jersey for N. Carolina, my mechanic drilled the precat and put sealer in. In a nutshell, this is what has happened since: -Drove 500 miles to n Carolina, started car next day no problem, 2 hours later very hard start. -Next day: Start car no problem, start car 2 hours later, very hard start(giving gas to boost rpms to start) -Next day very hard start, Bleed radiator lines, car starts fine. -For 2 days car starts fine. Turned off and on maybe 15-20 times running errands. -Next day car won't start. Checked spark plugs yesterday. 1 & 4 wet and smell like gas (from trying to start it and giving the car gas, I guess) but they spark and so does 3. No spark on 2. 2&3 dry with no smell. I am changing the spark plugs today, tho I very much doubt that will help. That is the limit of what I can do with my automotive knowledge and available tools(not sure what I have less of). If it won't turn over, I'll have to have it towed to a shop and hope for the best. I have 3 more payments on it, so can't even have it hauled away cuz I have no title. I am at my wit's end.

Replying to: tripj (Oct 01, 2009 9:12 am) Wow, $100 for a diagnostic, hate to see you spend that much, but may be worth it if they give you valuable information. This all goes back to the Head Gasket problem and if you have the pre-cat problem or not. Even with the sealer in the radiator, the Head Gasket will still leak small amounts of coolant into the cylinders from time to time, that is why you need to daily be checking all the fluid levels. Please update on how much coolant that you have to add per day or week, and how much engine oil you have to add per day, week, or month, this will be indications of what is happening with the head gasket leak and if there are any problems with the cylinders. That would be helpful diagnostic information. To save your engine for as long as you can, make sure that the engine never runs hot or overheats & check and keep all fluid levels filled up. Good Luck, E.D.

Replying to: tripj (Oct 15, 2009 7:30 am) Other immediate issues...the hard starting - The Altimas are known to sometimes have problems with the sensors and the MASS Airflow Sensor. Make sure that the Crankshaft Position Sensor and the Camshaft Position Sensor have the recalls done on them up to date and that they are working correctly. Check the MAF sensor to be sure it is clean and working properly. All of these things have been discussed in these forums, go back and read the past messeges, use the "search" feature to find what you want to read about using keywords such as sensor, etc. And finally, yes, I know about "keeping the proverbial fingers crossed" as I do the same every day, because my daughter is still driving her 2002 Nissan Altima 2.5S, and it scares me to death, especially now that I have been out of work for almost five months and have NO money to fix it. I say RATS of this darn Depression! I keep asking her the same questions almost every day, Did you check the oil today? Did you have to add any oil today? How much? Did you check the coolant today? Did you have to add any coolant today? How much? Yes, I certainly keep my fingers crossed, all the time! Again, Good Luck, E.D. in Sunny Florida

Replying to: electricdesign (Oct 16, 2009 10:52 am) Don't waste your money and time to fix that Altima. I already threw more than $2000 to fix it in less than 1 year since 66k miles. (diagnostics, head gasket, CPS, struts, catalytic converter, engine mounts ). Exclude the $1000 maintenance like new brake rotors+pads at 80k miles, transmission+brake+ radiator fluid flush, inner+outer tie rod +alignment, new alternator (bad bearing) . I hate it's loud tapping noise during winter and lean pinging sound under light throttle + oil consumption. I keep driving it with DIY maintenance for 2-3 more years. I am looking for a mechanics that can re-program the ECU to fix the lean detonation issue. I hate to go to STEALERSHIP (dealership) with $95 per diagnostic. |
