Rough Idle Need a Good Shop/Mechanic Options

[Jupiter]

My rebuilt (new head and belts, seals etc) 95 GT convertible is hunting for an idle around 800-1100 RPM and occasionally falters and dies.

When I got it back from the shop the second time ($2500.00 so far) they had cleaned out the throttle body and the cold idle was working for the first time in years but it was idling fast. Now it is back to no cold idle and it is thready on idle at best. Toyota wants $140.00 to diagnose problem and $550.00 to replace IAC if needed and it will be needed as well as who knows what else.

Tried the carb cleaner in the IAC trick, no help. Runs like a tiger at speed, but won't idle worth a damn....

Anyone know a shop that really knows the 2200 L in the Central California area? The shop that rebuilt the head just tightened up the throttle cable so it was idling (poorly) at 1400-1600 rpm.

Need a reference for a shop that actually knows Toyotas. It is a Federal smog set-up 2200L 5SFE 5 speed.

sorry you have spent so much for such poor results. Im too far away for you. 550 to replace the IAC is robbery! you could have a dirty injector, failing fuel pump. there could be a number of issues.

go to a junkyard and get a used IAC, there is a lot of members here that may have it just laying on the old engine. Just ask anyone that has swapped.

I'd suggest you try to re-set the idle stop and re-home the TPS correctly, it could be a simple issue.

Just posted this, but you should try it. It worked for me, maybe it'll work for you. Try to unplug the IACV plug first and see what happens when you do that.

Welllll ...... Cautionary tale here.

Took it to a good shop. IAC replaced, TPS re-set, coolant temperature sensor replaced, distributor was full of oil, replaced, cap, rotor replaced, sensor from transmission adjusted/repaired. $1500.00. Now I have $4000.00 in an engine on a car that is worth MAYBE $3500.00.

Drove car home from shop, running nicely until a few miles on freeway, temperature gauge was swinging up and down wildly, car running fine. Took it off the freeway... no antifreeze in car. Called shop, drove it last mile home, installed 1 1/2 gallon antifreeze, drove it back and blew an expansion plug on the way, though it was no longer overheating. Hell of a coincidence but you guys (mechanics) all claim overheating can't cause an expansion plug to fail. So does the shop.

Lesson.... If you can't work on one of these things (I can't) put it down or sell it to someone who can.

Shop says plug is not failing because they forgot to put the 1 1/2 gallon of antifreeze back in the radiator. Wasn't leaking ANYWHERE when I put it in before returning it for a courtesy check, I had run it in my garage for 10 minutes until the fan came on to make sure it wasn't leaking. Claimed the plug must have failed on my way home... it didn't 100% positive of that, can't prove it though since I don't live at their shop.

Started leaking on the way back. 40 miles round trip. Argued them into eating the 5 hours shop time and $4.00 for the plug to replace it, but not an easy argument to win.

IF they fix it I am going to sell the car. I have $4K in an engine "guaranteed" for 2 years 24k by the shop.

$3500. and count myself lucky?

5 speed convertible, lots and lots of expensive extras, most don't work. Cruise control, nope, power antennae, nope, power door locks and Clifford keyless entry/alarm, nope...

Nice body, needs some paint on hood and rubbed out, black. Beauty of the fleet if fixed up.

Federal smog living in California. Top is ok, rear window and cowl replaced a few years ago, leather seats no rips (replaced from a yard), windows all work (replaced one a few years ago as well as one motor). Anyone know what this car sold for new in 1995? Toyota claims there were no five speed convertibles built in 1995, and cruise control was not available in manual transmission cars. I am second owner.... First owner said car cost nearly $30,000.00 new. Story there somewhere.

Nice car for one of you.

I'll try here first.
