MOUNT STERLING,
Kentucky
To start, I have read all other sources of information that refer to anything with bogging on a 4G63T.
I'm sorry this post will be so long but I know details are key and I want to give you all everything that i know of the car for the best possible answers!!
I will give the full details of the car/mods then the issue.
I purchased this car very recently. To explain this in FULL I will refer to the previous owners and there mods.
Kevin/ Owner from 2015 thru November 2018
1. New Timing Belt
2. New stock Turbo
3. Replaced Water Pump
4. EGR Block Off
Apparently Kevin sells the car because it is no longer running and he does not know the issue.
Daniel/ Owner from November 2018 thru January 2019 (I bought the car from Daniel)
1. Walbro 450 e85 Fuel Pump
2. 101-100/101-200 cams (says completely new, I will include a picture he sent of them before I purchased)
3. NGK bpr6es spark plugs
4. Coil Pack
5. NGK Plug Wires
6. Oil Change
Daniel tells me he purchased the car not running and all he did was put a fuel pump on it and it started right up.
Daniel also tells me he has removed the A\C compressor and lines along with removing cruise control.
He has also cut of the exhaust directly behind the cat-converter
BUYING/ DRIVING HOME
I live in Kentucky and Daniel lives in Kansas. I found the car via craigslist a mere few hours after it was posted (I searched for these cars daily nationwide.... been wanting a 99 GSX for a while )
I drove to Kansas 630 miles away, and looked at the car. Upon arrival had to jump the car because Daniel said he had left the light on. Started right up tho and idled fine. (just loud) let it warm up for a moment and took it for a short test drive. (keeping in mind the temp is 15 degrees) Car ran great. Everything worked from the power seats, sunroof, to the heat. Put the car to the floor and it accelerated and rev'd completely fine.
Daniel gave me the Cat and o2 sensor he had cut off, He also gave me the cruise control, A/C compressor and lines.
After agreeing to buy the car I started the 9 hour drive home. Car still running fine. 30 minutes into driving we pull over to nap for a bit. 1 and a half hours later (the car was completely turned off during this whole time as we napped in the car we drove down in.) I wake up, fill the car with gas and hit the interstate. First chance I got to give the car full throttle, I did. BOOM!! Back fired really loud, bogging hard and no acceleration. I let off throttle and hit it again. Same thing. Car is running and driving very well other than when attempting to give it enough throttle to build boost. I continue my drive home and the problem continues the entire drive. During the drive home by feathering the throttle i was able to hit 105mph (anymore throttle was causing rpms to spike and the bogging would begin.)
Fast Forward to being home
I have done the following and the problem still persists.
1. Checked for visible obvious boost leaks
2. New Fuel Filter
3. Checked all Spark Plugs
4. Cleaned MAF Sensor
5. Oil Change
6. Reinstalled Cat-Converter and rear o2 sesnor
The car has actually gotten progressively worse. Ill explain my results by relating the #1-#6 i listed above and describe the car after each.
1-2
Car had no visible or obvious boost looks. All hoses and connections seem to be intact and tight. New Duralast direct fit fuel filter.
Car idles 1000rpms, runs and drives the same. (60-70mph is as fast as you can go now matter how you accelerate)
3-4
Spark plugs all looked good. Used MAF sensor cleaner.
Car idles 1000rpms, runs and drives the same.
While the car is running if you unplug the MAF sensor it bogs down hard at idle but seems to drive the same plugged in or not.
Still cant get past the 60-70mph
5-6
Had a local shop change the oil and put the cat back on. They also replaced the flex joint (old one had a small hole) They plugged up the rear o2 sensor as well.
Car idles rough at 500rpms, runs betterish, drives the same.
While driving and under decent throttle you still get the bogging really bad and the car does not accelerate at WOT. Plus side, you can give the car moderate throttle for a little quicker acceleration as opposed to literally having to feather it before.
65mph MAX
***Mechanic said the Cat had a crack on the inside
I have driven many turbo cars and had a 99 gst previously. This car is not getting boost under throttle at all or it definitely doesn't feel or accelerate like it is. You can definitely here the turbo begin to spool under slight throttle but then the bogging starts soon after. Also keeping in mind during all 6 things I have done thus far at idle you can rev the car to 7k rpms. sometimes it cuts out, sometimes it doesn't. The car currently has no gauges at all so I cant actually tel if it is building boost or not.
1999 Eclipse GSX
141,000 miles
Automatic
The car is currently reading the following codes when scanned
I have researched all of these codes via obd-codes.com and answered all of the possible causes that they list.
P0125 ENGINE COOLANT TEMP SENSOR
-Car seems to warm up fine
-Coolant level is fine
-Car does not have any visible leaks
-HAVE NOT tested coolant temp sensor
P0136 2nd o2 sensor on Bank #1
-NOT BEEN CLEARED SENSE REINSTALL OF CAT
P0141 HEATED CIRCUIT o2 Sensor 2 on Bank #1
-NOT BEEN CLEARED SENSE REINSTALL OF CAT
P0170 FUEL TRIM
-CEL is on
-Idles at 500rpm
-Awful MPG
-No black smoke
-Hesitates at idle and under load
P0403 EGR CIRCUIT
-Supposedly blocked off by Kevin (DONT KNOW HOW TO CHECK)
P0443 PURGE SOLENOID
-NO IDEA on anything here
P1104 TURBO WASTEGATE SOLENOID
-When giving throttle in park the wastegate doesnt move???
P1105 FUEL PRESSURE SOLENOID
-NO IDEA here
I will have the car rescanned this evening and all codes cleared. I'll report back with the remaining codes.
Any input, feedback, or suggestions at all would be extremely appreciated!!!!
Thank you all in advance!
