I have search this forum but was unable to find the information that closely pertain to my current D2 problem. Please share any feedbacks and thoughts on the following issue/s. Thanks in advance.
So i have been trying to be productive and attempting to fix my wife's 2001 D2 since her last episode when the truck overheated and went into limp mode on the same day. We actually had it towed to our driveway and that was 2 weeks ago. Here is the summary of my project.
2001 D2 with 124K we're the 2nd owner, truck was dealer serviced from new by previous owner based on the sales receipts kept. Head gasket & ABS modulator replaced at 71K. Bought at 105K a year ago and so far replaced the front DS and kept up with the PM
Parts replaced:
- Battery (warranty)
- alternator (reman) due to the voltage reading shown 11-12V while engine running MIL P1562
- idler pulleys (70MM & 80MM) when I noticed that the bearings started to go bad
- tensioner pulley (replaced with metal type) also noticed the bearings on the plastic pulley were bad
- drive belt since I found several cranks on the belt that were straight from end to end
- spark plugs due to SES came on and MIL code PO307 showed misfire from bank 7
- ignition wires replaced after the plugs since MIL PO307 came back
- upper inlet manifold gasket PM recommended
- O2 sensor (PS pre CAT)replaced due to code PO130
- top off coolant (50/50)still topping off once the engine cooled off & "gurgling" sound still present
I noticed the followings while working on the project:
- oil in the IACV hoses by the throttle body
- varnish color buildups inside the last 4 ports on the upper manifold; bank 4,8,5 and 7
- HT wire #7 seemed not long enough to connect to the plug and excessive carbon buildup with plug #7
- coolant by the valley gasket in the rear but not sure if this was from the spill earlier while disconnecting the coolant hoses by the throttle body
Test drive
On SUN drove up to 45 mph w/o SES coming on & topped off coolant
On MON noticed coolant low so topped off and drove up to 30 mph with SES came on and each time the engine "stutter" briefly
MIL codes PO307, PO130 and PO300 were all present! WTFudge!
