2003 Honda Accord Repair Question
2003 Blazer 144K v6 - help please!
Aug 06 - replaced serpentine belt
Jan 07 - tune up, change fuel filter, put in spark plugs [twice - they put in the wrong ones to start!], replace fuel injectors, replace fuel pressure regulator.
This fixed the check engine light that had been on since I bought it in August!
After all that it ran GREAT. For 3 weeks.
1 - chirping sound a few times a minute - reminds me of mice
2 - sounds like a jet engine off and on
3 - slight hesitation when speeding up/slowing down
4 - a bit of a rougher ride [the tire pressure is good according to the scale for cold tires]
The noise isn't enough to hear when the heater is on. The weather did drop to -38C [-50C with a windchill] - the only thing I did different was put in a bottle of gasline antifreeze when I filled it up. Its starting fine, no codes/check engine light [so no misfires right?]
I have tried it without the heater on [possibly ac someone told me] & the noise/problems are still there. I've also tried it in 4 wheel drive vs 2 wheel drive - exactly the same.
Is this due to the cold weather, a misaligned belt [the chirping?] ... or something drastic?? Thanks for the help
Doesn't sound like anything to pull your hair out over just yet.
The cold is problaby having an effect on the belt. The tensioner may be on the weak side as well. You can spray some belt dressing on the belt to see if it stops the noise, if not there may be a pulley bearing going bad.
Keep an eye on the temperature gauge and watch to see if the jet engine noise happens when it is about the same temp when it starts to happen.
Not sure on the hesitation, there may be codes stored that didn't set the CEL. Check your transmission fluid level.
The rough ride is probably cold related. When the truck sets the tires get a flat spot that freezes that way until the tires get warmed up and back to shape.
The ride is different when it is this bitter out.
