#76 of 85 Re: 2000 Chevy Venture Misfiring and SES Light. [fleastiff] by fleastiff Jul 17, 2008 (4:03 am)
Replying to: fleastiff (Jul 08, 2008 11:23 pm) I was not driving the vehicle at the time but it was described as 'making loud noises' and 'bucking'. For a cold, rainy morning and a short drive the temperature guage was very high. And it seemed to make a loud noise and generate a great quantity of smoke and/or steam. It may have been its death throws, I don't know.   I did determine that ALL the coolant was gone so there must be some sort of leak and the oil was about a quart low. After these fluid deficiencies are corrected, I intend to attempt a restart and see what happens. Maybe I will be able to resurrect the vehicle. Maybe not.

Replying to: 442dude (Apr 23, 2008 3:38 pm) >4. Bad head gasket... >but you already said your oil looks good with no coolant in it so I doubt this one Well, I think it WAS good, but now the head gasket is indeed blown and all the coolant is inside the engine. Mechanic is saying 900 for "new" engine and 900 for labor. 90 day warranty.   >leads me towards the fuel injector or the ignition coil for cylinder # 1. You were probably right, but all those Fuel Injector cleaning bottled only helped a bit and I guess I delayed too much in getting it to a mechanic to figure out the next step of actually replacing fuel injectors and testing coils and cams.   Once it lost all the coolant and got hot enough to send smoke/steam out the tailpipe and engine compartment, I figured something real serious had happened.   I do want to thank everyone for their assistance though.

Does any one out there know how to reach the rear spark plugs on a 1999. I heard the engine had to be dropped down an gotten from the rear. Replies to this message: 442dude (Aug 21, 2008 5:21 pm)

Replying to: vito5 (Aug 21, 2008 4:28 am) If its the same as the 2000:   Remove top front motor mounts (2) Remove throttle & cruise control cables from throttle Remove air intake plumbing Put trans in neutral Use ratcheting strap attached to engine lift lug and rotate engine forward about 20-40 degrees & hold Remove ignition coils Remove rear plugs
#80 of 85 Ignition coil replacement by chipper1 Apr 03, 2009 (12:23 pm)
Is it possible to change cyl. 1 and 2 ignition coil w/out removing air intake, throttle and cruise cables, but just a few inches w/ the ratchet strap? Replies to this message: 442dude (Apr 04, 2009 10:39 am)

Replying to: chipper1 (Apr 03, 2009 12:23 pm) I've never tried so I can't say for sure - it only takes a couple of minutes at most to remove the intake plumbing and the 2 cables so why take the chance of damaging something...
#82 of 85 From misfire to hell by chipper1 Apr 06, 2009 (7:37 pm)
Diagnostic read 'misfire cyl1' changed all plugs, wires, ignition coils. Still funky on idle, gave 3 doses + of cleaning additive, and changed air filter. next morning; 0 degrees to boiling in 3 minutes, replaced thermostat. NO Help. Now running super rough, and fluctuating between normal temp. and crazy hot to warm, Thermostat replaced by cert. mechanic. WHAT NEXT? Please help!
