s'ko Posted January 22, 2009 Share Posted January 22, 2009 (edited) I have been having problems with my 92 EJ22T. It would crank with out starting for about 2 mins or so and then it would start. I had a friend crank while I checked the engine during one of these episodes and found that there was no spark from the coil pack. I pulled the following CEL codes 13 Cam Angle sensor 14-17 injectors 1-4 21- Coolant temp sensor 22- Knock sensor 23- Airflow meter circuit 24- bypass air control valve 32- O2 sensor 41- Air/Fuel ratio control system 45- Pressure sensor duty solenoid. Car runs fine once it’s started. It will drive about 10 miles or so at highway conditions and then the CEL will light up. If I cut the engine off and then start it again, the CEL goes away. I don’t believe all of these sensors would go out or go bad all at once. There must be a common thing that is causing the error. Hopefully, it's not the ECU. Any ideas on where I should start? Thanks BW Edited January 22, 2009 by s'ko Quote Link to comment Share on other sites More sharing options...
nipper Posted January 22, 2009 Share Posted January 22, 2009 Hard Start is usually the TPS sensor. Clear all the codes and run the car again, then pull the codes. Alot of those are related by a common denominator of the car not starting when its supposed to. nipper Quote Link to comment Share on other sites More sharing options...
bgambino Posted January 23, 2009 Share Posted January 23, 2009 could a bad ground connection cause this? Quote Link to comment Share on other sites More sharing options...
nipper Posted January 23, 2009 Share Posted January 23, 2009 could a bad ground connection cause this? If he had a crank issue to yes, but its cranking fine it seems, so there is a good ground between engine and battery. nipper Quote Link to comment Share on other sites More sharing options...
mountaingoatgruff Posted January 23, 2009 Share Posted January 23, 2009 you'd be amazed what bad harness grounds did to my 93 imp. it'd throw codes on brand new sensors, run funny, shift crappy - and it cranked fine. definitely would not hurt to check the harness grounds.

s'ko Posted January 25, 2009 Author Share Posted January 25, 2009 spent some time today working on the car. The error codes are coming from moisture shorts. The harness is pushed through the body through the driver side fender and I did not waterproof the area well. when it dries up I will take some sealant and get it sealed up nice and tight.

s'ko Posted February 2, 2009 Author Share Posted February 2, 2009 additional diagnosis. Bad main ground to rear of the engine. The thick ground wire from the battery to the starter bolt was loose and causing intermittent shorts with the vibration of the car driving. YEAH.

s'ko Posted February 20, 2009 Author Share Posted February 20, 2009 The saga continues: The gaggle of CELs have been cleared. Engine is still running erratically. In first gear it would accelerate and then hiccup at around 4k-5k rpm and then continue to accelerate. Doing a corner and downshifting to 2nd and gunning it will produce stumbling. It would also lightly stumble a bit when cruising at freeway speed. Only error code I found was number 32. O2 sensor. I tried unplugging the sensor to see what it would do and the condition did not change. Replaced the O2 sensor last night. Initial test drive around the block was great. No hesitation and no bucking. I was a happy camper at 11:30 last night. This morning going to work. Felt very sluggish. I tried a full throttle run and the boost spiked to the top of the gauge and the car just made a lot of engine noise. I am guessing it was roughly 20 lbs. stumbling like a drunk sailor. The bucking got a little worse and I noticed a cloud of smoke behind me. Slowing down, I smell burning oil and the smoke started to bellow through the hood scoop. Pulled over and the smoke was all over the place and there was a huge pool of oil in front of the car. I am thinking blown HG, or worse rod through the block. I removed the spark wires from the coil and cranked the engine and there was no scary knocking sounds, maybe there's hope. AAA came and towed me home, when I looked underneath, I noticed that the oil return line from the turbo to the head had come lose. So this is why it was hemorrhaging oil before. Re-connected the return line and filled it w/oil. Started car. Ran ok. Revved it to 4k. No knocking, so looks like I didn’t kill my engine. Now idle is a over the place. It goes from 2k down to under 1k and then it jumps around to the point where it will almost stall and then it will recover. Took it for a brief test drive and it stumbles pretty badly while under 3k. Once above that, it drives ok. Will not go into positive boost. Ohh and the oil that was chilling on the exhaust/down pipe makes it look like it’s on fire. Where to start looking, Grounds are good.

bheinen74 Posted February 20, 2009 Share Posted February 20, 2009 coolant temp sensor.? timing belt on dead on correct? maf sensor cleaned. do you run a K&N air filter, those throw oil on to the MAF and cause this. what kind of plugs and plug wire Quote Link to comment Share on other sites More sharing options...
s'ko Posted February 20, 2009 Author Share Posted February 20, 2009 coolant temp sensor.? not sure. it's the one that was on the 200k motor I got. Will check it when I get home timing belt on dead on correct? new belt and pulleys with the rebuild. pretty sure they are dead on, but I can always checkmaf sensor cleaned. do you run a K&N air filter, those throw oil on to the MAF and cause this. what kind of plugs and plug wire have new OEM style filter and running new denso plugs, wires unknown, will look into replace them. Will add them to my list of items to check BW Quote Link to comment Share on other sites More sharing options...
bheinen74 Posted February 20, 2009 Share Posted February 20, 2009 its the T belt......will put money on it. yep. my 92 was sold to me with this problem. He said, that he checked the belt, no matter what, he could not get it to run, many new parts, new ecu, injectors, wiring, even the shop said t-belt was okay as it was newer. Well, I didn't trust anything, and checked it myself the right way. Yep, fixed that, and well, soon after, the clutch let go...... thing screams.

I am reluctant to call it a t-belt problem b/c it ran really good before the ground problem developed. It passed smog and pulled strong all day long. Sunday will tell me more about what is going on.

s'ko Posted February 2, 2010 Author Share Posted February 2, 2010 I know it's a year overdue, but someone asked me the outcome of this problem. The first problem was due to a bad ground. The wire behind the starter was loose and would vibrate causing an intermittent short. The second problem with the erratic acceleration is not completely resolved. Switching the O2 sensor helped, but I think it is due to some wires getting damaged by the turbo up pipe. It doesn't happen often enough to warrant a complete rewiring of the harness near the lower radiator support. Some times, I will get a stumble when I have the right turn signal on and I accelerate at the same time. The third problem where it was driving retarted and then blow the oil return line was due to a retarted mechanic (that being me). Forgot to connect the boost sensor. Other than that things are running great w/the RX. Took it to Las Vegas on Thanksgiving weekend and even drove it home on Sunday after Thanksgiving . The traffic is so crazy, it makes a 4-5 hour drive into a 8-10 hour crawl. Never overheated and ran like a champ. BW Quote Link to comment Share on other sites More sharing options...
