#376 of 427 sluggish acceleration
Apr 06, 2010 (12:59 pm)
I bought my 2000 chevy s10 4.3 4x4 a year ago with 49000 miles. It ran like a dream until about a month ago. I now have 58000 miles and recently have been experiencing a drop in power when accelerating. In March I had a magnaflow muffler installed and it increased the juice, but now im losing that juice. It will speed up gradually until about 3rd gear, then it loses power at about 2500 or 3000 rpms at 50mph and needs to kick into passing gear to make it to 60mph. Could this be an engine problem or tranny?

Have your catalytic converter checked for plugging.

Hello Forum. i have a problem thats concerning me. when i drive my truck to work in the morning (its usually a 30 minute drive to and from) after 15 mins of driving i stop at a red light and when it turns green i give it some gas its seem like the gas doesnt go to the injector and starts to make a "boom boom boom" sound.. so i put the car in neutral and turn off then on the car and its works. same thing happens coming home from work. does anyone have a solution? thank you in advance.
Friends tell me to check the gas filter. could that be the problem?
#380 of 427 98 S-10 2.2L misfire

I have a 98 with a 2.2L bottom end rebuild and new head installed. I bought the truck not running guy thought it had bad set of rings. I find when i took it apart that had a hole in the head next to valve guide seat. New coils,plugs,wires. It still has misfire on #3 I have moved the injector on #3 to #1 no change. replaced all o-rings on injectors. Fuel pressure is where it should be did compression check had 175 LBS on all four cylinders. Did leak down compression check and they where 12% to 14% on all cylinders. Moved coils around and had no change. I have checked continuity on all injector wire back to pcm. checked voltage to module to coils have 12 volts. I have pressure checked intake manifold to 30 psi. Still can not find the problem. PLEASE HELP!!!! I'm running out of ideas.

Put a noid light on #3 and see if the PCM is commanding the injector on.

I did that and it was flashing. On a scanner that a friend has he can tell the injector is firing a 4.3 milliseconds the same as the rest.

My guess is the TPS (throttle position sensor) - good luck!!!

I have a 2002 S-10 4cyl. and had the same problem especially when it rained and was damp out.... it was very frustrating. It went on for several months. Finally, I found a mechanic who knew what it was. Coils! Replaced both of them had NO problems since!
Six cylinders have 3 coils
