#5 of 374 Running Rough by wmoses3818 Aug 23, 2002 (8:56 pm)
I have a 98 S-10 extra cab with the four-cylinder motor, manual transmission and approximately 90k miles. My truck has been completely reliable up until a few weeks ago. The motor would noticeably miss and then seemingly smooth out and run fine. It got progressively worse; primarily when I would began accelerating after stopping at a stoplight. It misses, but accelerates slowly, and once up to speed it runs fine. I had the dealer check it out and they replaced the plug wires and spark plugs. The problem continued however the dealer said it was fine. I brought it to an independent shop and they replaced the fuel filter and inspected and cleaned the injectors. Still the problem persists. Both shops claim that there is not a problem and everything is fine. Any advice would be appreciated; I am at my wits end. Thanks.

#6 of 374 '94 S10 Overheating Problems by canyon_run Sep 05, 2002 (12:20 pm)
I have a '94 S-10, 4 cylinder, manual, 95,500 miles that has an overheating problem. I have changed out the thermostat twice, the fan clutch plate and the valve gasket seals, and have no air conditioning. It only occurs when the outside temps are humid and above 85 or so. It occurs on the freeway and town streets and only cools down after running the heater on high, but continues if I turn off the heater. Has anyone else had this problem that can make some suggestions, as the garages/ dealerships cannot seem to figure out what's wrong with it.
#7 of 374 Constant Overheating by softwarevp Sep 06, 2002 (10:30 am)
I have a 96 S-10, 4 cyl, manual, 62,000 miles that had an overheating problem as well. It finally overheated quite a bit, so I took it to the shop only to find out that either the head gasket needs replaced or I have a cracked head. Might want your mechanic to check and see if any steam is coming out of your tailpipe. Do you have to constantly top off your coolant levels??
#8 of 374 Hard Starting by mattison1 Sep 09, 2002 (6:20 pm)
My 98 S-10 blazer is start hard in the mornings and after sitting for more than 30 min. When it is running it runs fine. I have replaced the plugs, had the throttle body ckecked, and had the electrical system ckecked. So far I have found nothing. Any ideas welcome.

#9 of 374 Overheatin by canyon_run Sep 11, 2002 (3:41 pm)
The coolant levels are good - that's one thing I've learned to check constantly with this problem. I haven't noticed any steam but I will mention it when I take it in (again) next week. If it's a cracked head, you'll be seeing it on the side of the road. Thanks for the suggestion.
#10 of 374 2.2 engine vs 4.3 by go10go4 Sep 14, 2002 (1:02 pm)
I am shopping for another S-10 used. My last had a 2.8 engine V-6 - EXTREMELY reliable. Almost 200,000 with NO engine repairs. That's no longer available. I'm having a hard time finding a 4.3; almost all seem to have the 2.2 4 cyl. Any experiences with these engines? I have heard the 2.2 is underpowered. Is it durable?

#11 of 374 Faded Mirrors, Grill & Door Handles by chevy_s10_ls Sep 16, 2002 (5:53 pm)
Just got a 99 S10 LS Extended cab.   Both mirrors, parts of the grill area and the door handles have started to fade from their original black color to a chalky gray'ish/white color. Any suggestions as to what I can apply to them to bring back the dark black color.. or am I resigned to buying all new parts?

i used a dry scouring pad to clean the black on my plastic grill and metak wipers, then sprayed them with a black primer. i'm not sure about your mirrors though. black primer is actually dark grey and comes in a spray can.
