97 SL ATX - Not firing on cylinders 3 and 6; no voltage to that coil.
I've checked:
Plugs
Wires
Coils
PTU
ECU
Timing
So I guess the CAS is the next best guess. So where exactly IS the CAS...and how do i test it? Also, where is the timing mark on the crank pulley? Cams are all aligned but I didn't see a mark for the crank and don't know where I should be looking.
I have a 1995 3000gt sl. When im on the freeway running at 80 mph and maintaining that speed it starts to overheat.I can reduce my speed and it starts to cool down I can also turn heater on high and that cools it down I cant hit the exit ramp and by the time I get stopped at the end of ramp its cooled back down.I can start it and sit with it running and it never gets hot.If I stay below 55 I never have any overheating its only when I increase and maintain 75 or faster I have a problem. Also when it was hot outside I turned my air on max cool one day and it got hot real fast.So to fix that I just didn't run my air any more. then a few months went by and this started to happen.50mph and slower its fine.But at freeway speed limit it starts running hot. Only with increased speed to the engine does it start getting hot.
View 14 RepliesI have a 93 3000gt VR4 with 214,000 miles on her at the moment. As I am cursing at a speed of 55 the check engine light comes on and stay on for a while then as sudden as it came on it goes off still driving at 55 or less depens on traffic. My question is why is this happening? I took it to AMMCO to have the code check but they could not because the check engine light is not constantly. I do not have a code sxanner for the car to read the codes if any. The engine runs strong I tried to see if I could get the check engine light to come on but to no avail. Could it be a sensor going bad or the ECU I had trouble with it before and had the dealer replaced it.

View 4 RepliesAl right i have a 94 ranger 4.0 4x4 auto 186k ... The truck has new bosch double plat plugs gaped .054, new wires, MAF, TPS, FPR, O2 sensors, ECTS and I checked the intake air charge sensor and is fine ....
My issue is cylinders 4,5 and 6 dont fire... the coil is sending a spark, i can pull the plugs one at a time and watch them fire (strong blue spark)... All fuel injectors do not leak and spray a perfect cone out of all 4 holes and noid light test is good ...
The truck runs like crap back firing and no power under 4k and i can pull off all 3 wires for bank one and it make no difference and when i unplug the injectors no more back fire....
Why the reverse lights goes out?
View 7 RepliesYesterday when I was on my way to a funeral, I noticed that whenever I braked kind of hard there would be a lot of noise and vibration on my car. The noise seemed to be coming from the front passenger side of the car and seemed to pull to the right a bit. I pulled over and took a look and everything looked fine but the sound and vibration was still there.
I drove about 10-15 minutes tops like this, parked the car, did the funeral home service, and 2 hours later while driving to the burial site (about 20 minute drive on the streets and freeway), everything felt fine. No vibration, no noise, nothing.
After the burial site I drove another 15 minutes to my parents house but this time you could hear the sound faintly and only when I braked hard. I jacked up the car and took off all the tires to take a look at the brakes/rotors and everything looked ok. I had plenty of pad left and the rotors seemed fine. With the tires on, I am able to spin the tires with my hands no problem.
This morning I drove to work and had no issues at all. No sound, no vibration, nothing. So at this point, I am stumped at what could have caused the noise and vibration earlier yesterday morning.
My ecu capacitors leaked all over my ecu board which is normal for the 1gen 3000gt's. A guy from work who had the proper tools was able to hook me up and fix the board, so far so good.

View 1 RepliesNeed to locate and resolve the backfiring problem When I drive the car. I changed the lifters and smoother out the throttle body and install a new fuel filter and lines. the car ran fins until is missed shift and stalled the car. I then read on one of the forums that the coils could be bad so I changed all of them plus the O2 sensors. and the car idles fine but as i put it into gear it sluggish and backfire. I have change all that I know to except the spark plugs and wires. I'm thinking something maybe wrong with the computer. I don't have any diagnostics equipment. Is my engine ready to die?
View 2 RepliesBuying a vr4 this weekend with dr650 turbos... The only problem with car is when you shift into reverse it grinds and won't go into gear, I'm thinking its the reverse synchro?
View 2 RepliesWhile driving home from work tonight a light on my dashboard began flickering when I was turning into the freeway. It is the far right set of lights, the third light from the bottom (or top as I believe there are only 5 lights/slots there)...
I have a 94 SL.
The auto trans on my SL has been shifting hard and jerking lately, and the other night it wouldn't shift into 4th at all and I got a CEL code having to do with the transmission solenoid. So to my question; how hard is this solenoid to replace, and were is it located? Also, need to get part number? Additionally, I check the fluid every few weeks so I know that's good, and it seems to get worse (more jerky) when its hot.
View 3 RepliesI think my car has a vaccum leak. The car cranks ok, but it has a lope to it and when I try to drive it, it hesitate when I step on the gas and sputters, every since I cleaned the engine. I checked all the vacuum lines and found two that were broken or split. I replace those lines I also check the air intake vinyl connection to the throttle body it wasn't slpit. Well I didn't see a split in it. So I put it back together and cranked it. You can hear a vacuum leak sound near the fire wall. I pulled each vacuum line off one at a time and checked them again and found nothing. Could this be the intake plenum? I hat to take it to a mechanic when it is something simple that I could fix.
View 4 RepliesMy 95 3000gt is smoking after about 30 minutes of driving. Smokes mainly when idle and upon acceleration. car has about 200k in mile. what could cause this.
View 5 Replies3.0, SOHC engine...car started for coolant system leak check. Idle jumped to. 3000 RPMs. Shut car off...disconnected throttle cable from throttle body. Started car again, engine ran normally, no coolant leak found. Reconnected accelertor cable to throttle body. Tried starting car again, started rough then died after a few seconds. Changed fuel filter...disconnected fuel line to fuel rail and lots of comes out. MFI solenoid inside car clicks several times after engine dies. Engine tries to run, but wont, after it dies. ECU bad? Other issue?
View 4 RepliesSo I had this issue with my idling at 1300 rpms but every now and then it would idle at 400 and barley run then one day it didnt want to idle at all so I checked the iac and it was bad so I changed my oil, fuel filter, iac, cleaned my throttle body, fixed a vacuum hose, and cleaned my air filter.
When I started it it idle at 2200 I drove it a little and it dropped down to 1300 the next day I started it and it idled at 800 and staid there for four days now it idles at 2000 then will drop down and surge between 1300 and 1800.
I read that the oil you apply to the filter can contaminate the Maf and you should clean it but a lot of people said the one on a vr4 can't be cleaned while others say it fine. Is there a way to check the maf?
I have a 91 Mitsubishi gto TT. I love my car and i was really hoping to repaint it soon but this problem is becoming more apparent. My car runs fine for the first 15 minutes, runs like a beauty! but then once it is warmed up it starts to struggle. I cant accelerate hard because it hesitates alot. The problem im having is pin pointing the problem. Ive searched a lot of stuff on the web and some people have similar problems.
Could it be bad spark plugs and wires causing some cylinders not to run properly? If so then why does does it run fine for the first 10-15 minutes?
I'll probably have my plugs and wires changed to see if that changes anything.
I just dont understand why my car accelerates great when cold but when hot starts to run sluggish.
I bought a 01 passat with a bad turbo I drove it home as I was getting home the STOP low oil pressure light came on and I parked it the engine had a lifter rattle but not knocking I went to start next day and Have no fire on first two cylinders (only two I checked), where to start? I pulled coil pack/plug tube out and hooked a plug in to check fire on first 2 cylinders got no spark....
View 1 RepliesOk so I'm having weird issues with my big turbo R. I thought I was having misfires in low rpm range. Car was stumbling and just not firing on all cylinders ( just an expression but that's what it felt like) realized it was because of the esp. Ok no the main issue. Vacuum was sitting around 14hg. When I come up to a light or stop sign or just put in neutral while moving it revs it self ad vacuum will go to almost 0hg until I come to a full stop.
The rev is not a big rev only like 100-150 rpm increase. Also the throttle response is not there if I go to rev match down shift. Here's the weird part. If I unplug the Maf it runs super smooth 19-20hg vacuum amazing throttle response clutch chatter almost goes away. There are no cel with or without the Maf plugged in I have logs for both...
150K 2003 durango 4.7, ran like a top, backed in my driveway to eat lunch. Went to start and it sounded like it was firing on 1 or 2 cylinders give it a little gas and it died. Repeated 3 or 4 times now no fire at all. No check engine light at first now it flashes. About 30 miles with new fuel from a reputable local station tank was on reserve ( 0 miles on the overhead indicator ). All fuses are good . could it be a relay.....
