Ticking / Clicking sound under acceleration
On my '02 4R w/ SC I am hearing a ticking sound when I accelerate. It sounds like it is coming from the right side around the glove compartment area. This is a new sound and happens at very low speeds --- 0-30+ mph. I figure it is some odd anomaly and _not_ a PING or KNOCK. It can't be a speedo cable noice because it is on the _right_ side. Any one experience this?

Yeah, I decided on using the search feature and this was the closest match to my situation.
I get the ticking when at the begining of acceleration when I lightly press on gas. I discovered it driving around in a parking lot looking for a spot. Goin pretty slow. Dont get the noise when Im hard on the gas or coasting. Maybe its jsut drowned out when I get on the gas.
Ill note the RPM later today and get back to you. But off the top of my head I think it happends from 500-1500rpms

Ok I noted that the ticking happens in all gears from 1500 to about 2500 rpms. At its peak, rpms is at 2000rpm with ticking fading after that.
Any Ideas? Could it be pinging due to DR Z mod with capped FPR?

My best guess right now would be to seal up your airbox and reinstall your paper filter, then see if it continues. Also, I did not realize that doing the ISR mod would require caping the FPR. That does not seem right to me. Did your preignition start right AFTER you did these mods, or at least the last mod you did? What was the last mod you did?

Here is a link to updated ISR MOD

It didnt start right after the mod and that was the last mod I did.
Ill try higher octane.

What octane do they tell you to use in your owner's manual?
Galen told me that he did not think it advisable or fruitful to use the ISR on my SC'd engine, BUT it did improve performance and I am pleased with the mod. I told him of my observations. Also, it did not create noticebly more intake noise. Good luck unraveling your mystery.

The deck plate mod with factory air box and OEM filter made my 99 Limited clack, tick and knock (whichever you prefer) under heavy load at low RPM's taking off suddenly, you could also pop the throttle at idle in drive to ask something of it and hear an obvious engine clack, put the deck plate cap back on, no clack ping or tick, I noticed no performance gain using the deck plate mod. My 97 SR5 has just a cheap oiled cone filter and no clack tick or pings ever just different injectors for that year I assume, both vehicles run well and are well maintained. Are you Supercharged like the OP from 2003.
