I'm looking for someone with extensive experience with Hondas. Specifically I need someone who can figure out why my 93 VX is doing the part throttle hesitation at operating temp (doesn't do it when cold).

The car has:
Correct timing
Recently adjusted valves
New plugs,
New OEM honda wires
New distributor/cap/rotor
New fuel filter

I originally thought it was the 02 sensor but I changed it out with no change in the hesitation. Next thing I thought was, it could be the EGR but I had a mechanic run some tests and he said the valves are opening and closing just fine so it's not that and that he thinks it could be "weak clutch springs" and I should just drive it at higher RPMs because it's a Honda and they're made to rev high :/ When i told him it's affecting my MPG as well and i'm losing 10mpg from 46-36mpg he says "Oh, well that car should be getting in the 30s no problem I don't know about it getting that high mileage." wtf??

So... I'm tired of dealing with dumb ****s excuse my french. I need a HONDA specialist. help plz!

 

damn id fire that guy sucks gl bro

 

You need to find someone who can graph the tps. I don't have the equipment to do it. But when the sensor gets hot it could he malfunctioning.

 

hmm I was thinking of replacing that but it seems like a bitch to remove

 

Not really I've replaced them before. Pretty easy.

 

how'd you retract the screws?

 

Make a slot to put a screwdriver in.

 

ah... ok so say I do that, get the new TPS in. What about adjusting it to the proper specs? I read somewhere on here that you have to do that.

 

Yes you do. If its not adjusted the car will run funny and waste gas.

 

TTT... still need a mechanic. It's not the TPS, MAP or EGR valve :/

 

Did you have the tps graphed or did you replace it?

 

it's not the TPS because it runs fine when the 02 isn't plugged in. I have a thread going on about this. it's not the 02 either.

 

Maybe you need to check for shorted wires. weird issue you have

 

It's your iac idle air control it's on the manifold about $30 used on at junk yard call Honda heaven off penrose on the 5 freeway in valley.

 

Lol iac valve would not cause his problem.
