| Just bought a 2000 Protege ES 1.8L with 5 speed manual, 84K miles. The car runs well but the idle speed seems low (maybe 500 rpm), and the car idles roughly and seems to want to cut out, but never has so far. Previous owner said his mechanic told him it needs idle adjustment. The car was had been in a minor front end accident about a year prior and has a new radiator. There is an intake assembly running from the air filter housing out to the actual air intake on top of the radiator. This was apparently never put back right after the accident, and the tubing doesn't connect well to the filter housing, so that the actual air intake is probably taking place at the base of the housing. I could fix this easily enough, but there also seems to be an opening on the bottom of the tubing, so that either way I'm not really going to be taking in air from the assembly over the radiator. My questions: 1) Should I adjust the idle, or should I try to fix the intake first? 2) What should the intake setup look like? Is there really supposed to be a hole at the bottom of the tubing right as it connects to the air filter housing, or is there supposed to be another hose or something there? If anyone has a car like this and can take a photo of what the intake is supposed to look like, I'd appreciate it. Thanks. | |

96 Mazda Protege LX 1.5L with 104,000 miles, (past) due for timing belt replacement. timing belt tensioner cam seals crank seal valve cover gasket timing idlers water pump Estimate totaled $370 for parts (from Advance, not Mazda parts), $200 labor - this all by a friend, independent unemployed mechanic working on his own. I was then advised that if anything "went wrong", etc., this could create a bad situation (for me) as there would be no liability/responsibility for anything that might happen. After contemplation, I decided best way to go would be where I could get a warranty on work (parts and labor), so got a shop estimate of $630 with same parts. Mazda dealer quoted $900, but after hearing previous estimates, convinced me to bring car in for them to check and they would work with me, convincing me they could get cost down to at least mid-$700s or probably even lower. Another shop quoted $260 labor plus cost of genuine Mazda parts which should make total around $700 +/-. Took car into dealer, they tell me I don't need tensioner (would save about $65 for Mazda part per online research), added additional belts bringing total for parts/labor to $770 and intake "boot" (can't find this online - is it same as valve?) for 85.78/no additional labor, now back up to original $900 quote (actually $932.78 with taxes). I do feel warranty is important as I cannot afford to put out more money for re-repair and have no other means of transportation. Do you know if Mazda parts carry their same warranty if service not done by a Mazda dealer/mechanic? I have owned Mazdas for several years now, but this is highest mileage and most major work at one time that I have ever had done on one, so I guess that is what is causing me the most stress, but would really appreciate your opinion. I can't get a definitive answer on what they are charging for labor (as they tell me it varies from $95/hour, but less than that for this type work), but it seems that is the major cost difference, appearing to be (from quote of $260 of other shop) to what appears to be closer to $500 with Mazda, and they tell me they have worked to get the price down and are basically "cutting me a deal"?? Am I getting a good or reasonable deal for the work listed? Two more things they found that will need replacing soon are a thermostat gasket (quoted $225) and distributor cap which is leaking minimal oil now (quoted $150). I was also told by them that my car is in extremely good condition for age/miles.

Replying to: kaymt (Jul 25, 2008 3:54 am) I think genuine Mazda parts would have a warranty no matter who installed them but you'd have to demonstrate defects is materials and workmanship, and of course the LABOR is not warrantied by Mazda if an outsider installs the part. I know some very good indie shops so I'd be inclined to save the $300 and go there rather than the dealer, but if you don't have strong confidence in the indie shop or any idea of their reputation, then the dealer is really your only logical choice. |

I have a 94 protege 194k miles dx automatic. I have had this car for about 3 months and it has been great...until I parked it one night and when i got up the next day and cranked it it was sputtering and knocking it will not idle and when i try to drive it there is no power. If I put it in park and floor the accelerator it will only go to about 3500 rpm(still sputtering) and almost sounds like it is flooding.When I got the car I put new plug wires,plugs,dist cap and rotor button on it and accessory belts. I am disabled and only drive the car about 20 miles a week. I thought it may be fuel filter so I replaced it and removed the injectors and cleaned them still the same problem...help please,thanks.
