While driving my jeep it will jump out of gear, do not know if its shifting into in overdrive of not. I have to pull over and work the 4wheel gear in order for the manual drive to engage any idea what might be causing this.
Working on friends jeep she had battery light come on and started heading home about 30min 25miles later overheated and stalled.. i went the next day and pulley was loose replaced water pump and coolant started car and it was jerking running rough. Pulled codes p0300(multiple misfire) P0700(transmission control module malfunction) and p0562 (system voltage low). I replaced the spark plugs and battery still ran rough at idle but ok going down the street almost stalls between drive and reverse and at stops. only took out to refresh codes since battery disconnect. New codes are P2305(cylinder2 misfire) p2311 (coil 2nd circuit number4 cylinder) and p0123(TPS detects high volts… now i had pulled all the coils once and,checked the tps when i was diagnosing looking for any heat damage and also to see which coils were not affecting when unplugged. I cleared codes and all im getting now is p0175 p0173 which is rich exhaust detected by o2 sensors but the three it just showed weren’t there anymore… now she ordered 2 coils and a TPS and went to a mechanic who tells her its blown up wont be specific at all he claims its got no oil in it however i checked the levels and they were fine before i left it parked there without TPS or the two bad coils in it so she couldn’t drive it how could it be blown also how could it not be blown because I’m no certified mechanic but i know a lot and i didn’t think it was blown up beyond repair it was still starting, and idling before i removed those parts..? Suggestions opinions help?!?!
I have a 97 jeep wrangler that was built in November so I think the motor is a 98. ok the problem is after about 20 min of driving it acts like its chocking out and dies. after a few minuets it will start but just idle. when it is cooled off completely like the next day it will run for 20 min. or so and do it all over again. I have replaced the sensor under the distributor cap and the crankshaft sensor but it still dose it.
Recently bought an 88′ Cherokee XJ with a 4.0. When I went to go see it wouldn’t start. But after unplugging and re connecting the CPS it ran but really roughly. Idles low at around 200-300 rpms. Replaced the tps, cleaned throttle body and IAC, replaced lower O2 with the upstream on order and installing soon (was pretty nasty). Also have a MAP sensor just installed as well. Replaced the dreaded CPS and still no major improvement. The valve cover gasket looks like it needs to be replaced. When I rev it up then let off the gas it usually kills it but will start back up and continue to idle roughly. Also replaced fuel filter. I’ve done some slight adjustments to tps but it really only either cranks rpms up to 2500-3000 rpms at idle until I kill it, comes close to killing it or has it idle like usual. Any ideas on would be greatly appreciated. I’ve done a lot of research but so far efforts have not seen any real results. PO installed tps so maybe I needs to be correctly adjusted with multi meter?
I have this jeep Cherokee and before we changed the oil on it was fine but we just changed the oil and it started to make a weird sound like if it was coming from the muffler. Would you happen to know what it could be?
I recently replaced the upper radiator hose, thermostat, and heat sensor, now the new upper radiator hose is being sucked flat, what do I need to check to resolve the issue?
air conditioner pressure valve keeps blowing freon out whats the problem?
yesterday my car lost gears 4-6 in “D” mode, i was able to drive using manual 1-6. later on the car had no issues, should i have this checked out anyway?
