Thank you , For the first 5 month after the replacement if the injectors, I had any problem. This problem begins with the strange noise that I can not fix the source but I will check the resistance of injectors to be sure that is not the reason of my problems... Thank you for your help I...

Hi , Since some times, my car has rich cold start situation. For the first 3-4 sec , the car cold starts perfectly with approx 900 -1000 RPM. Then RPM decrease to 800 and I can feel the engine not comfortable and smell the gas from exhaust pipe. This situtation continues for 20-30 sec then...

in closed loop ( enters in close loop, I think , after approx 167 degree fahrenheit ) engine uses voltage signals from O2 sensor ( s ) . until 89 there is one O2 sensor on left exhasut manifold , maybe there is 2 or 3 for year 90 and 91 of L98 .... First to check is o2 sensor in my...

Probably it is not related to fuel pump becasause, if fuel pump stops, it takes some seconds to finish the fuel in the rail and begin to surge and stops atfer all this. It is like , you lost electrical source and engine stops after that. When you try to restart , it restarts immediatly or do...

4900 RPM is NORMAL ! after 4750 , it is orange in some condition you can maybe see 5100 RPM but not so much, L98 is not designed to rev high RPM's , low RPM high torq is its speciality ), Regarding your description, your car shifts correctly , more you accelerate, late it will upshift. NORMAL...

Hi ! The throttle valve cable ( TV cable ) control line pressure in the transmission . If it hit hard, it must to be adjusted. Sometimes, it is not easy to find the right place to stop the adjustment system ( the TV cable passes from this adjuster ) . Imp : It is not natural that it hits so...

Hi , If your steering become hard, it means that for some reason ( power steering pump or rack and pinion itself ) you lost assistance pressure ( pump related ) or fluid pressure does not make the job ( rack and pinion related ) . On my 88 I had a similar problem , - I change the pump >...

Correction ! You transmission is a 4L60E ... you don't have a TV cable. So please forget my message but the diagnose with high pressure line still here :)

Hi ! it seems that you have high line pressure inside the hydraulic body of the transmission . I don't remember if it is a 4L60 or 4L60E for 1993 model year I think 4L60 E begins on 1996 ... ) , Probably it is a 4L60 which means that you have a throttle valve cable attached to the throttle...

Hi Ted and Ken Mohr ! I reply an old subject. As you did , I also replaced my 238 degree aux fan switch with the TFS4 and also the connector which was cracked. Here is my observation : As it should , the aux fan kick on at 215 and kick off at 205 but the problem is, in these conditions...

Hi ! The middle of the gauge is 13 V , and between every little line , there is 2,5 V Even the gauge is not linear for analogue gauge, the optimum reading must be logically between the middle line and the first little line after the middle ( 13 V ) line. At startup , you can read 15 V...

Thank you Ex-x-fire, I will try to find also something to clean the MAF , there is not enough staff special in Turkey and no way to order it :(( ( I change more then needed the air filter , but I have a new MAF Burn - off relay that I think to change it also )

Thank you Surfer93 , I already check the vacuum house , there is no sign of gas in the hose , so it is OK I Think , but if I change the injectors, I will also put a new diaph on it because it will be not an easy job to remove all the plenum etc .. I don't know if I will do it by myself

Thank you very much Hib Sometimes ago , you have already say me that my injectors are leaking , it is time to replace them now :) I think the stock rate is : 24 LB / Hr , MR ex-x-fire says that the decrease of 4 PSI within 10 min is normal ? you don't agree with this opinion ...

Hi from Turkey , Istanbul , I have an 88 with 76.000 original miles. When my car stays more then 5 min and I come back , it difficult to restart the car. When it restarts, there is black fume and fuel smell . There is no problem for cold start or restart hot within 4-5 min. I ordered fuel...

Problem is still here :( There is one thing maybe a guideline : When the car has done this first, the average fuel cunsomption was 12,8 litre/100 . While the problem is here, instant fuel consumption is 0 ( zero/100 ) but the average consumption indicates 12,8/100 , value of the day she did...
