Hey y’all, I’m hoping someone might have a little insight into a particular problem I’ve been having with my 2001 Corolla.
The car had been idling a little rough lately and I’d noticed a drop in MPG. After trying a few easy fixes I finally replaced the O2 sensor a few weeks ago. The idle has leveled out but ever since then I’ve been getting periodic hesitant-to-non-existent acceleration. Sometimes it works just fine (better than it’s been in years, actually) but then sometime it will take forever to accelerate from a stop. I’ll give it some gas and it will just roll forward at barely more than an idle for half-a-block until something kicks in and it levels out around 30mph. This doesn’t happen consistently though and I can’t see much of a pattern in when it happens or why. It seems to help a little if I ease into the gas very gently, and it is worse when I try to gun it. I was worried it might be the fuel injectors or the ignition coils but I wanted to see if anyone else had dealt with this issue before I go down that expensive route.
I appreciate any ideas you might have. Thanks!
