I have a 2007 Dodge Nitro 3.7L 4x4 base model with about 135,000 miles and I like it because its loud and it is a 6-speed manual and it’s fun to drive unlike some of the other cars I had. I bought it used and someone did not take care of it, within a year I had $2,000 in repairs, had to replace a headgasket the next year $1700 (worked some overtime to pay for all these), currently I spend on below $1000 in repairs a year, I figure that its cheaper then depreciation on a new car or even a newer car. Recently it broke, I seem to be fixing it a lot, In the past I had electrical, a/c, and cooling issues, before I took it to the mechanic I tried to fix it myself, AutoZone said it was the camshaft position sensor, and I replaced the camshaft position sensor, after replacing the camshaft sensor I had a difficult time starting it, and I cranked it a couple times for about 10 seconds, after about 10 seconds it started but ran rough with a gas smell. I towed it to my mechanic and he had to replace the ECU because of a short in a crankshaft sensor cable, the cable came apart from the heat of the exhaust, mechanic says it ran on 3 cylinders. Crankshaft sensor and cables from the Crankshaft and Camshaft had to be replaced also. After the fix my Nitro has much more power and runs like a new car, after owning it for 5 years it finally runs like it should, before the shifter would vibrate and I thought it was normal with less power, the cable that lead to the crankshaft sensor must have had a degraded connection. After the fix I noticed that there was sometimes a beeping when I took the key out of the ignition, I troubleshot the issue and I had a sticking ignition switch, I sprayed some WD40, like you said in your videos and that fixed it. Since my mechanic fixed it, about 2 weeks ago, my Nitro, sometimes, it starts on the second crank. I could take it back to my mechanic, I have a good mechanic, but don’t want to keep spending money on it all the time if I can fix it myself. Why would it start on the second crank sometimes? Should I keep starting it on the 2nd crank? Should I use some Fuel System Cleaner? Also, its almost impossible to reach the oil filter to change the oil on those, what or how do you recommend to change it? How often should I change the oil in the drive axles? For the rear can I just siphon the oil out and refill or do I have to take the entire drive axle apart?
I just realized that Dodge Nitro does not have a MASS airflow sensor, throttle was already cleaned. It does have an IAT sensor.
For your starting on 2nd crank, do this, the Scotty will guide you through it. Old toothbrush, rags. Do TB, MAF and PCV Valve, easy cheap fix w/ brilliant results. You'll be pleased:
